I have a simple question. I dried my jacket on a high temperature in the dryer. Everybody tells me I shouldn't have done this, but how will it affect my jacket? Adrien Lancaster, United Kingdom

G'day Gear Guru, I've noticed a couple of innovative water-purifiers that incorporate the filter mechanism directly into the cap of a light, convenient, and squeezable water bottle. Models by Orinoco and SafeWater Anywhere make lofty claims of filtering and purifying the nasties better than traditional pump-style filters; the SafeWater model even has a filter cap that fits onto Nalgene bottles. Is there any point to lugging around our old pump filters anymore? Lange Sydney, Australia

Oh Gear Oracle, I have a problem with a build-up of moisture within my mittens, not from rain or snow, but from my own perspiration. This is especially true during snowshoeing trips. I was wondering if there are any shells that have little or no insulation, allowing me to layer them inside and increase the breathability of the mitten. Dennis Portsmouth, New Hampshire

Oh Gear Guide, you have failed us! Over and over I have heard you espouse the quality of the Yashica, so I decided that the T4 was the camera for me. Unfortunately, after hours of searching, I find out that the T4 has not been made for years! Just recently, you suggested the camera but didn't mention that it would be impossible to find. With the T4 no longer on the market, what kind of camera would you suggest? Mike Newark, Ohio

At what point, if ever, should your boots be replaced? Is it a question of mileage, time, or condition? I've had my boots (L.L. Bean Knife Edge, leather) for a number of years. They are well maintained and comfortable. Is there a point where the boot does not perform its support function and the trade off between comfort and support (in favor of comfort) is not worth it? Jim Comerford Wyncote, Pennsylvania

Your Gearness, I'm in desperate need of your expert advice. After two major knee surgeries involving saws, metal plates, and screws, I have suddenly become an advocate of trekking poles. I own a set of Master Kompressor poles with comfortable handles and a useful shock-absorber option. However, I've been tempted by a pair of Leki Ultralites, which are six ounces lighter but without the shock absorbers. At five-foot-one and about 120 pounds, do I really need poles with shock absorbers, or is it a waste of money for me? I have my sights set on the Grand Canyon this spring and would like to have time to "road test" a set of poles before then. Paula San Diego, California

I have been trying to decide between the PUR Guide water filter and the MSR MiniWorks, although I have heard that the MSR clogs less and is cleanable. However, the MiniWorks' high pump per liter ratio has turned me off, especially as the PUR Guide boasts a more efficient output. I will be using the filter mostly in high alpine areas where the water is fairly clear of mud and silt. What are your thoughts? Jim Huntsville, Utah

What are the key factors one should take into account in purchasing a road/touring bike? Brent Ithaca, New York

I want a chest pack to carry my Pentax 67II camera and its lens. It will need to have padded shoulder straps and a strap to hold it tight around my waist. Any ideas? Kiim Clackas, Oregon

I've been looking at water purifiers and have narrowed it down to two-the First Need Deluxe and the Sweet Water Guardian. I've read some on both and I've heard of the Guardian breaking on hiking trips and not being field serviceable. I haven't been able to get much info on the First Need Deluxe, only that is clogs. Which do you think is better and why? Kyle Waco, Texas

Is it better to roll or stuff a tent? Kye Eugene, Oregon

I'm considering purchasing a food dehydrator to help lighten things up on long hikes and bike rides. My research suggests that the best options are the erican Harvest or the Excalibur, but I have no idea of how these compare or if there is a better choice out there. I'm comfortable selecting the price and capacity of the model, but at a loss when it comes to the other nuts and bolts of the subject. Do you have any insights that can inform my decision? Chuck Freeport, Maine

Why are mountaineering leather double boots such as the Boreal G1 or Vasque Vertical such a niche product? They are supposed to provide as much warmth as plastic double boots, without any the discomfort of wearing something fit for Frankenstein. These boots have summited Denali and Everest, yet event the "experts" at specialty gear stores frequently don't know about them. What's the catch? Andy Veres Alexandria, Virginia

What's your take on Backpacker's Pantry Outback Oven? Does the Outback Oven really bake well and also conserves fuel for cooking traditional grub? After a zillion meals of mac and cheese, ren, gorp, and dried fruits, the Ziplocs carrying the food start looking more appetizing then the food within. The idea of dining on hot cinnon rolls, fresh pita bread, pot pies, or (gasp!) brownies does make me wonder if the Outback Oven really works or if it's just another ravenous hikers delusions? Ed Beaudry Laurel, Maryland

Years ago you recommended The North Face Snowshoe sleeping bag to me, just the ticket for a dp 58 hours in Lapland's freezing rain! Since your record is one for one, I seek your advice again for a compact, light sleeping bag (down is out due to allergies) to use when backpacking in Croatia in August. We'll be sleeping hut-to-hut while walking in the countryside, while also spending some time in cities. Do you think Design Salt's silk liner is good enough for such a trip, or do we need an ultralight sleeping bag? Jan Helsinki, Finland

I would like to know what the difference is between Marmot's 800-fill Couloir and 600-fill Never Summer sleeping bags if they both have a rating of zero-degrees. I'm going to Patagonia in January and would like to know which bag you would use, although I'm not yet sure what elevation I'll be at. Hans Norton, Massachusetts

What's the scoop on Eureka's Zeus EXO line of single-wall backpacking tents? They're inexpensive, light for the square footage, and look to have the se super-quick setup as the larger Eurekas. Do you have any info on how well these tents vent? Bill Charlottesville, Virginia

A friend and I are planning an attempt to summit Mount Shasta this summer. Neither of us owns an ice ax or crampons and we plan to rent those items when we get to the area. But recently I've been looking at Kahtoolas, which are kind of "crampons light." They're aluminum with no front points and touted as compatible with everything from hiking boots to running shoes. Looks like they might be adequate for a trek up Mount Shasta. Also, I might get some use out of these in future winter hikes. But they are north of 100 bucks (in the same territory as some entry-level crampons). Do you have any experience/insights on Kahtoolas? Mitch Thompson Shaker Heights, Ohio

What's the best tent for winter camping? I'm interested in a two- to three-person tent that's lightweight, packable, and available at a low price. I will be spending time in northern Massachusetts and the White Mountains this winter. I've been looking into single-pole shelters like the Black Diond Betid ($98), and while comfortable with not having a sealed floor, I worry about water seeping in. Do these tarps really work? Are they reliable? Is it possible to find a reliable four-season tent under $200? Boaz Sender Boston, Massachusetts

I need to find a tent for winter camping and mountaineering. Living in Oregon I intend to stay within the Cascades. I have narrowed my search to the Fusion 2 and the Fury 2, both made by MSR. They fall into the same weight/price/size category. The Fusion is a convertible tent while the fury appears to be a four-season tent. Given the conditions I'm expecting to face, which tent would be the ideal choice for me? Is the Fury too much tent, is the Fusion too little? Is there another tent that you would recommend? Kevin Portland, Oregon

I'm a 40-year-old dad planning to be a mule for my young family of five (wife, two daughters, ten and 12 years old, and seven-year-old son). I'm looking for a large capacity (6,000-plus-cubic-inch) backpack. I'm currently looking at the Osprey Crescent 110, Dana Designs Terraplane, and Arc'Teryx Bora 95. I realize pack comfort will differ based on individual size and body shape. Of these three I mention, and possibly others I haven't, which carries the heaviest loads and provides the most comfort. Frank Hahn Chula Vista, California

I'm curious to hear your opinion about Osprey's line of Ariel backpacks, particularly their Ariel 75. I can't seem to find any reviews on anything other than the Aether 60. I loved the Osprey Luna 75, but I'm looking for something slightly lighter. My main concern is whether the suspension of this smaller pack will hold up under a 40-pound load. I don't want to sacrifice good load transfer and stability simply for the sake of a lighter pack. Erica Boston, Massachusetts

This summer, I will be traveling in Peru and concerned about thieves cutting into my pack. What do you recommend to protect my belongings? Pat Harlingen, Texas

I'm planning an Appalachian Trail through-hike for 2003. I've poured over all the gear columns/ratings/etc. And with a bit of your wisdom have narrowed down most of my gear. But...I'm thinking of going stoveless. What's your opinion and do you know any recipes for easy/light/nutritious stoveless meals? Tim Moose, Wyoming

I'm hiking the Grand Canyon rim to rim this spring, and I'm wondering what footwear to use. I like the lightness and cushioning of the trail runners that I've been using for my ten-mile training hikes, but I'm wondering if I need something a little more burly for my unsteady legs over the course of the 24-mile hike. Any thoughts on the Lowa Tempest? Jay Phoenix, Arizona

OK, this is a serious question. You seem like the kind of guy who does a fair amount of biking in cold, windy places. I've recently started to use my bike to commute to work and have noticed a "small" change in a very personal area. The wind goes right through my pants, and when I arrive at my location my little guy is tucked away like a scared turtle. This isn't a real huge problem, just inconvenient and uncomfortable. Do you know of any underwear or pants that could help fight this problem? Karl Rostock, Germany

Dear Gear Guru, Each year I spend more and more time engaging in technically demanding backpacking, backcountry skiing, and mountaineering trips into the remote backcountry. Due to my exposure, the natural dangers of the mountains, and the probability of accidents, the need for a reliable and durable communications system has arisen. Do you know of a system that has long-range communication capabilities and can withstand the needs of being both portable and durable? Is a satellite phone the answer? As always, I look forward to the wisdom of your responses. Sean Constine

I would like to buy a digital camera to bring on climbing, canoeing, and hiking trips. I had been planning to buy an SLR, but I've recently been tempted by digital cameras and their ability to make you impulsively take snapshots. What factors other then weight and picture quality should I consider? Any help you can give me would be much appreciated. Eric Winnipeg, Manitoba

I looking into buying a soft-shell jacket and interested in the Cloudveil Serendipity, the Arc'teryx Gma, and another jacket from Salomon. What are your opinions on these jackets and are there any others that I should consider? Mike Kane Rock Island, Illinois

Does anyone make a waterproof tight for inclement weather running/cycling? InSport used to make one, but I guess it went the way of Activent. A European company supposedly makes something called the RaidLight tight, but I can't seem to find anyone who carries it. Erin Skowran Belleville, Illinois

What do you think of OR's Pulsar Parka? I see the Outside Buyer's Guide gave it a "Drool" award. I ask because I can't find it for sale at any of the "big" outdoor retailers. I have hunted every major Web site that carries OR products and not one of them carries or even advertises this jacket. Was there some problem with them or why does no one carry them? Thank you for your response. Craig K. Noble Bliss, New York

What have you heard about the new Eureka Zeus Exo1 single wall Tent? I a big Sierra Design Meteor Light CD fan but need a very lightweight tent for a solo through-hike this summer. Thanks for your help! Lora Cochran Cody, Wyoming

Can you shed some light on headlps for a well-intentioned fanny-pack kisser? I'm after a good, bright headlp for hiking and backpacking. I have an old Princeton Tec Solo, but thinking of upgrading to a Black Diond Gemini or one of the Petzl models. And there I was thinking that the days of headgear obsessions ended with high school. Jay Eugene, Oregon

I'm planning a trip to the Bahas this summer and in the market for a reliable diving watch. Can you recommend something that won't implode after the first ten meters and won't shatter my bank balance? Alison Austin, Texas

My husband and I frequently take our two dogs on our camping trips, in all sorts of weather. However, as much as I love them, after a day of hiking on muddy trails I'm often less than enthused about welcoming two balls of mud into our tent (one 20-pound beagle-ball, the other a 60-pound lab-type-ball). We have daydreamed about a lightweight pouch or lightly insulated sleep sack for our dogs. I ready to start experimenting with my sewing machine, but a friend told me there's a company that makes this stuff. Is this true? And if so, is this gear practical? Toni Schenectady, New York

I'll be going to England, Ireland, and Scotland soon and will spend most nights in my tent or in hostels. My question for you is: what kind of pants should I bring? I want them to look good (since I'll be touring museums and all that), but still be lightweight and durable, since I'll be using these on backpacking trips in the future. I think I've narrowed it down to two choices: Ex Officio Explorer Pants and Royal Robbins's Go Everywhere Pants, but I can be persuaded to change my mind. My girlfriend (who goes with me on many of my trips) thinks zip-off pants look completely dorky, so I'm not interested in those. Thanks for any information! Steve Bockhold Memphis, Tennessee

Are there any leather boots that will hold up on the "big peaks" like Denali or Everest? I planning a trip to Denali and would really like to go with leather boots as I've never liked plastics. Any thoughts? Jeff Norfolk, Virginia

What are the best boots for snowshoeing? I've tried winter boots and cross-country ski boots, but none of these fit well enough in my snowshoes. Jean San Francisco, California

I going kayaking in two week's time to Big Bend. As I've never done it before, I'd like to know what gear is needed so that I don't freeze in the water. Luis San Antonio, Texas

Would you recommend a waterproof poncho for backpacking? My friends and I are thinking of doing the West Coast Trail on Vancouver Island this summer. I have heard that even the best Gore-Tex fails under the onslaught of seven days of heavy rain. Previous trail users have suggested carrying a waterproof poncho to cover you and your pack. What are your thoughts on this idea? Chris Barnes Silverdale, Washington

I just recently got into mountaineering and assing all the gear needed to pursue my different interests. I have a lot of the basics and now its time to get some boots. I need a four-season boot for both general mountain travel and technical ice. In the grand scheme of accruing mountain gear, boots account for a pretty hefty chunk of change—especially if you buy three pair of boots: one for three-season mountain travel, another for winter mountain travel, and the third for technical ice. Much more appealing would be a single pair of boots that could do all three. Does such a boot exist? If not, can I get away with two pairs of boots? I'm just looking for a way to escape throwing down $1000 on boots. Josh Hattan Lincoln, Nebraska

I looking for a winter jacket that some may call extreme. I bought a down jacket a few years back that was supposed to be good for -40 degrees Fahrenheit but whenever it is around below zero and a little windy I feel like I have a light fall jacket on. My dre coat would be a down jacket rated to -70 (then I might be warm when it is -10). To top it off I would also like it if it had a fleece liner for extra warmth that I could take in or out depending on the weather. Is there a place that either makes such a jacket or could custom make one? So, I too extreme? Glenn Mulno Needh, Massachussets

I need a bike for commuting that I can use with panniers. Should I go with a traditional touring bike, or should I use one of the hybrids similar to a Trek 7700 FX? I'd like to spend less than $1,250 if possible. I have found some bike commuting pages, but they don't give much guidance on, of all things, bikes. I'm sure you have more than enough time in the saddle to offer some guidance as well as some personal preferences. Tim San Jose, California

I was out hiking in the west Texas desert a few months ago during a delicious spate of rainy summer weather. I was wearing a light pair of boots and found myself slipping and sliding all over the wet rocks. Crawling on my hands and knees over boulders is not my idea of fun, and it really ruined my week. I'm now in the market for a pair of light "day hikers," with soles that'll give me some traction on wet rock. Any suggestions? Paul San Antonio, Texas

I'm looking for the perfect sea-kayaking tent. Currently I'm using an older The North Face Geodesic three-person tent: it's great but is on the large size and tends to leak when not staked out. So, I'm looking for something that packs into a small size, can hold more than one person's gear, sets up easily, doesn't require much staking (sand doesn't hold stakes very well), and is very waterproof. Marshall Watkinsville, Georgia

I recently started taking my dog with me while backpacking, and he loves it. But, should I worry about him drinking from lakes or stres? Should I filter his water for him? Kevin Mississauga, Ontario

I have been looking at jackets and vests from GoLite, and they all seem pretty cool. Logic tells me that their stuff probably doesn't keep one as warm as the heavier stuff other companies offer. Can you confirm that? Matthew Sattah Chattanooga, Tennessee

Do you know of any fully waterproof/breathable gloves made of two- or three-ply Gore-Tex? I'm looking for a glove that I can use for mountain biking when it is 40 to 50 degrees outside and raining hard. I'm not looking for a full-blown expedition climbing-type glove because I won't be out when it's 0 degrees. I've seen the Seal Skinz waterproof gloves but the outside material will retain water pretty much like a sponge. Steven Fleisig Upper Montclair, New Jersey

I've heard that deet will destroy nylon and nylon-blend materials such as tents and quick-drying garments. Is there an effective insect spray that can be used on these materials? Mike Tpa, Florida

There is a well known canoe camping writer that advocates using a plastic ground cloth on the INSIDE of your tent. He says that not only will you be drier in a downpour, but that it will protect the tent floor just as well as if it is placed underneath the tent. What are your thoughts on this subject? Dave Cbridge, Minnesota

I'm really getting into ultralight backpacking, and I hope to do a through-hike of the AT or PCT in the next few years. I do all of my backpacking in the summer, but my Marmot sleeping bag is too heavy (and warm). What choices are there for a light, compressible bag costing less than $100? If there are no bags in this range, would you recommend removing some of the down from my Marmot bag to make it lighter? Tom Bellevue, Washington

Why don't sleeping bag manufacturers make the outer shells on their bags from the se materials used in waterproof-breathable jackets? Thanks for your time and answer. Steve Youngsville, Louisiana

My wife and I like to share a cozy sleeping bag while kayak camping, but we both own "pre-marriage" bags that don't zip together. What we want is one bag wide enough for two, made from synthetic material (since it might get wet), and with a temperature rating of about 20 degrees. Also, as we're both about five-foot-five, it would need to be on the short side. Is our only choice to have a bag custom-made? Andy Kirkland, Washington

I starting to gear-up in preparation for climbs of Mount Baker and Mount Rainier this summer. I have an older Princeton Tec headlp that I use for backpacking, but can you recommend a good replacement? Are any of the newer LED headlps good enough to use when climbing? Kleet Renton, Washington

I have been happily skiing and snowboarding in my Patagonia Nitro II pants for the past few years. However, having recently signed up for a mountaineering course, I was told they aren't designed for mountaineering because of their two-ply, mesh-lined material. I'm confused as to why pants perfectly fine in a skiing environment can't work for mountaineering. I don't want to shell out $300 on another pair of pants! Ken Toronto, Ontario

Can three-season tents be used in the snow? Is it necessary to have a "mountain" tent for snow camping? With a full cover fly, what is wrong with using a three-season tent for occasional snow camping? Lyn Greenhill Roseville, California

So, after a year or so of ultra-light backpacking, my wife and I are starting to bring my son along, which means I need a huge pack to haul accommodation for three. Should I splurge and get a high-volume expedition pack like a Bora 95 or Gregory Denali, or are one of the new generation of external-fre packs (like Kelty's 50th anniversary edition) better value? We'll be mostly on trail, but I'm not sure if the lower-priced packs will provide enough comfort over a few days. Robert Granada Hills, California

I guess this might be more of a biological or physiological question than a straight gear question, but I notice that when I sip water from a CelBak, I have to "go" less than if I take bigger yet less frequent gulps from a water bottle. It seems that even drinking a full 70 ounces from my CelBak, compared to a quart from a bottle, is easier on my bladder. I just imagining this? Does the body better optimize water that's sipped slowly? Bill Bedford, New Hampshire

Not really a gear question, but can you tell me about all the pre-packaged trail food on the market? What have you tried? What's the best? Also, do you know of any Web sites with a good selection of trail recipes, especially vegetarian? Melissa Greenwood, Delaware

I'm planning on through-hiking the Pacific Crest Trail and would like to keep my pack weight as low as possible without sacrificing comfort. When I through-hiked the Appalachian Trail in 1990, my pack weight was around 50 pounds, including food and water. I have heard that ultralight packs are not very comfortable with loads over 20 pounds. Can you recommend a lightweight backpack for my hike? Cliff Ashford, Alabama

I'm gearing up for an ascent of Denali in May 2002. Could you advise for clothing and size of compression sacks appropriate to bring? I weigh 114 pounds so I want to minimize what I have to pack. Jeanne Stawiecki Charlton, Massachusetts

As a frequent trail runner, I looking for a backpack designed with running in mind. I would like something with ple storage for additional layers and supplies, certainly larger than a lumbar pack. Any suggestions? Connor Ann Arbor, Michigan

What's a good, moderately priced tire for mountain biking in the snow? I'm not looking to spend a fortune for a studded snow tire, just something with better traction that I can use in the spring as well. Paul Patterson, New York

Where can I find a waterproof video camera, for filming surfing and other stuff? Luke Ft. Myers, Florida

We know your favorite sub-$500 camera is the Yashica T4 Super. But, what are your favorite point-and-shoot cameras for $500 and above? Roy Boston, Massachusetts

I'm wondering if you know the difference between all the soft-shell fabrics, specifically Power Shield and Schoeller Dryskin. Also, what's the deal with the ultralight rain shells like Patagonia's Microburst or Arc'Teryx's Sirrus SL? REI's Web site used to say that Sirrus SL is "truly an ultralight shell, thus should not be for everyday use." Are they suggesting the ultralight jackets are not that durable? Does it make sense to carry both a soft-shell and an ultralight rain shell on a long backpacking trip? Jenny San Diego, California

My son is travelling to Costa Rica. He wants to take a small camping stove with him. Do you know what kind of fuel is available in Costa Rica and can you recommend a particular stove? Debbie Walker Vancouver, British Columbia

I interested in buying rappelling gear and I unsure as to what I need. Is there anywhere that I could find a list of must-haves for rappelling? Todd E. Clyde Hurricane, Utah

I looking to buy my first mountain bike and the more I look, the more frustrated I get. I've read some reviews in biking magazines, as well as Outside's March 2003 review of full-suspension bikes. Anyway, I'm looking for a full-suspension model with smart or rear-suspension lockout and good components (disc brakes would be a plus). Here's the kicker though: I looking to spend around $1,000, give or take a few hundred. I don't think that's unreasonable, so do you have any suggestions? Alex Hayward, California

I have been unsuccessfully combing the Internet for a pair of boots that possess a few specific features: full grain leather, a waterproof-breathable membrane (e.g. Gore-Tex), and a gusseted tongue. If you can help me find a pair of such boots for under $150 please tell me where! Lucas Mead, Washington

Help. After a winter of commuting by bike, my helmet stinks. I wear a helmet cover in the cold so sweat tends to accumulate and my head sweats a lot. I have tried washing it with antibacterial soap, but that only helps a little. I afraid of spraying Febreeze or other chemicals on the helmet's interior because I don't know if they would effect the safety of the helmet. And now my wife says that my head is beginning to smell as bad as my helmet. Before I either have to get a new helmet or sleep in the garage, is there anything I can do to get the smell out? Kevin Dalton Calgary, Alberta

I've recently been in some heated discussions with fellow campers over whether it's warmer to sleep naked in a sleeping bag or to wear some loose clothes. Logic would seem to suggest that more layers equal more insulation, but a surprising number of acquaintances swear they're warmer naked. Can you give me a definitive answer?

I'm a woman with very small wrists and have had great difficulty locating an altimeter watch that I can actually wear. Are there any smaller altimeter watches out there designed for women? Tally Rockford, Illinois

I just recently returned from a failed Mount Rainier attempt feeling deflated because my Koflach boots chewed up my feet before we even got to Cp Muir! I've been reading about the Asolo AFS Guide boots and they sound great. Where can I purchase these and will they work with a smaller, narrower woman's foot? (Living in North Carolina, I will have to play mail order.) I also tried some Lowas to no avail. I'm going back for another Rainier attempt next summer and would hate to fork out another $800 and not even make it to base cp. Karla Greensboro, North Carolina

What sort of cookware will I need on two- to four-night backpacking trips in the Appalachian backcountry? Kenny Birmingh, Alabama

Long time read, first time question. I'm a skinny guy. I love to ski, mostly at resorts but a little OB. My question, then: Is there a jacket-shell combo, or maybe just a jacket, that would keep me warm when it's zero degrees and windy, breathe when it's not that cold, and not make me feel like the Marshmallow Man? Timothy Rockaway, New Jersey

Is Gortex XCR a form of Activent that has been taped and se-sealed? Activent is a great product, totally windproof and highly water resistant, but wouldn't this have been waterproof too if it had been se-sealed? Herb Morganville, New Jersey

Is it sometimes desirable to hang your stove, for cooking in your tent? If so, who makes the devices to do this, and is it specific to stove model or is there a generic one? I own a Peak Apex II. Ron Starrett Vernon, Connecticut

Dear Gear Guru, Here is a question that no one ever talks about: the dreaded first aid kit. Of course, you'd never get injured, but in case you did, what do you recommend packing in the way of first aid for weeklong wilderness trips? I have looked around and can't find a pre-packed kit that seems very comprehensive. Andrew L. Salt Lake City, Utah

I'm going to a mountainous part of New Mexico this summer. On a previous six-day trip I took a pair of Asolo 535s, but this time I'll be trekking for about 12 days, in addition to a couple of shorter hikes to get acclimated. Since my old pair will need to be put to pasture (they deserve it), I'm wondering if the Asolo 535 will be tough enough for a longer trek, and also whether a pair of thicker Montrail Vercors boots might get too hot in New Mexico. Dave Charlotte, North Carolina
