I just bought new ski boots and I love them. Next on my list is buying new skis. I a solid level-nine skier and can ski anything on the mountain (New England or Rockies), although not always as gracefully as I would like. I love moguls but don't want a ski that submarines in powder. I was looking at the Salomon X-scres but heard that their tails were too stiff and therefore a lot of work in the bumps. Do you have any recommendations for top-of-the-line skis? Will New York, New York

I'm an Australian looking to travel in North America from December to February. Can you recommend a good trekking tent for the season that will house two to three people and their gear? I would like to use the tent year-round and for it to be fairly roomy. Rod Sydney, Australia

I looking for a new lightweight backpack. I never carry over 30 pounds and had decided on the Gregory Reality until I found a new Mountainsmith backpack called the Mountain Guide at a local store. The salesperson told me it was brand new and can't find any information about it. She weighed it for me as the specs didn't include a weight and it ce out about two pounds lighter then the Reality. Does two pounds makes a huge difference in a pack? Kjaristy Salt Lake City, Utah

I recently purchased quite an expensive digital camera. As I'll be backpacking in Montana's Crazy Mountains this June, I'm wondering if it's practical to bring the camera along. If so, what type of bag or protection should I purchase, and where is the safest, yet most accessible spot in my pack to store the camera? Kristin Eden Prairie, Minnesota

If I want to go mountaineering up here in the Northwest, is it enough to slap some crampons onto a pair of Scarpa Rios? I know Rios are great for just about everything else and that they stopped making the Edwardo climbing boot (why, I don't know). Or, should I try some other boot? Jim Trueworthy Coeur d'Alene, North Idaho

Backpacks are a bit of a problem for me because I rather well endowed and the straps get pushed out onto my arms when walking—with all the consequent chafing. Can you recommend a pack with front crossover straps, or an alternative that leaves me unchafed? Deborian Boca Raton, Florida

What's the best way to clean my hands in the wilderness prior to handling contact lenses? My waterless hand sanitizer warns against eye contact and I don't want to use stream water.

My daughter is flying to Europe this fall and is looking for a good all-around pack for all travel essentials, plus a computer. She is small-fred, five-feet four-inches tall, and weighs 110 pounds. This is the only luggage she is taking and she plans on being there five months. The packs needs to be durable and easy to carry. What should she be looking for? Janet Boise, Idaho

We're searching for a pair of sunglasses with a protective nose shield for a friend who has reoccurring skin cancer. Can you help us out? Tmy Tarentum, Pennsylvania

Last summer, I bought a Shan light touring kayak from Wilderness Systems (based largely on your recommendation, O Great and Wise One). After some great day trips, I'm now planning a multi-night river trip, so I'm looking for some packing advice. The boat has a rear bulkhead and an air bag up front for flotation. Should I pack my gear at the back with extra stuff lashed atop the stern, or can I replace the front flotation bag with a tapered dry bag? Zippo Baltimore, Maryland

A couple years ago I bought a Condor tent from The North Face, being informed by the salesperson that it was a four-season tent, although I have since discovered that may not be the case. I planning a June mountaineering course in the North Cascades that requires a four-season tent. Will my TNF tent suffice? I haven't used it for a while and lost the instructions, so do you know how I can contact them? Russ Frostburg, Maryland

I do much of my hiking in northern California's poison oak-covered hills. Usually I can avoid getting oaked, but after a day of tromping through this toxic weed, just how long do its oils remain active on my boots, gaiters, and trekking poles? Has science determined a half-life for poison oak's poison? Carter Napa, California

I use a 1968 Pinarello road bike. So, I was on a nice ride when I heard this "boing" noise; before I knew it, the derailleur (I think it was the original) had tangled in the wheel. The derailleur is now in two pieces, so I need to replace it. Are there any brands or models you could recommend? Can I put new gears on such an old bike? Could this have been prevented? Anthony Green Bay, Wisconsin

I thinking of upgrading my steel fre road bike to a carbon fork. I have tried a carbon fork in the past, and found it to be somewhat unsteady at high-speed (40 plus mph) descents. I weigh 185 pounds-does weight have a lot to do with the choice of a fork? Any suggestions? Should I just save the money and stay with my tried-and-true steel fork? Steve Weinberger Spokane, Washington

I've been doing some research on altimeter watches and have come across a lot of bad reviews for watches that I thought were good. Which watch would you recommend between the Casio Triple Sensor Pathfinder, the Timex Helix Works, and the Suunto Vector (some guy told me the workmanship on this was terrible and it fell apart)? Nadav Jerusalem, Israel

Are there any one-person tents that you can combine to make into a two-person tent? Denise Centennial, Colorado

In search of the Golden Boot over the years, I've owned disappointing Danners, Limmer mid-weights that ate up my right heel, and a forgettable pair of Meridians. I have a fairly low-volume foot, and while my current boots—a pair of Vasque Sundowners (Gore-Tex old style)—work pretty well, my feet still get hot spots and ache after a 12-mile walk. What's the boot for me? Stephen Decatur, Alabama

I'd like to invest in a pair of waterproof-breathable pants for one- or two-week treks where I might encounter rain and snow. Ideally, the pants would not be too bulky as they might spend quite some time in my backpack (I hope). If possible, please note any brands that I can find in Europe! Nicolas Heverlee, Belgium

My Boy Scout troop is planning to buy some rappelling gear, but we need some advice first. Eric Shelbyville, Indiana

I'm looking for info on bike trailers, having checked out some B.O.B. models, the Yakima Big Tow, and Burley's Nomad. Any insights as to which one would be best for city commuting? Also, any suggestions for where I might look for a used one? Linda Olympia, Washington

I currently have an older version of the Tubbs Sierra snowshoes, but I find them to be too bulky and heavy for those trips where crampons are also required. How does the MSR Denali snowshoe compare to its competitors, and what is the "floatability" factor of the MSR snowshoes? It seems they're very narrow, so I'm curious if they will keep you from sinking in soft, deep snow. Scott Newmarket, New Hampshire

Will a pair of electric socks, worn inside waders, work when I'm steelhead fishing? More importantly, will these be safe if I'm wading in water? Ed Pawling, New York

I've got a Bibler Betid tarp, and looking for some extra protection for my Mountain Hardwear sleeping bag (down with Conduit SL shell). I don't want to carry the Betid's floor since it is a bit heavy, and doesn't offer the protection I want. Please suggest a sleeping bag cover or bivy that will allow my bag to breathe, yet shed any moisture from condensation or the occasional exposure to rain. I'd prefer not to break the bank on this, as well. Dennis Staley Englewood, Colorado

What are the alternatives to Gore-Tex? Are there any that stand out from a protection as well as breathability perspective? I would love a Gore-Tex shell, but cannot afford to drop $400 on one. Alex Charlotte, North Carolina

Do you know of any evidence that pepper spray is an effective defense against a mountain lion attack? Mike Rapid City, South Dakota

I have an aging Columbia anorak shell that I'd like to replace. The problem is that I'm having trouble finding any new anorak-style jackets. I don't mind pulling the thing over my head and love the big front pocket. Any suggestions for a replacement, something I can use when hiking, climbing, and skiing? Chris Albuquerque, New Mexico

Where can I buy a hip belt to use as a harness for pulling my homemade gear sled? Bruce Easton, Pennsylvania

Dear gear swi, I'm looking to get back into mountain biking but have absolutely no clue about mountain bikes these days. I haven't ridden one nor done any research in about six years. If you could reach into the vast knowledge that you call a brain and offer some advice on bikes in range of about $1000, I would be in great debt to you. (And I would prefer a hardtail.) J.R. Venice, California

I have a few trips planned in bug-infested territory. The problem is that I hate DEET. I just don't like using the stuff. And citronella-based products are useless. Is there anything new out there that is effective, safe to use, and won't melt plastic? Jake Santos Chicago, Illinois

In November I'll be doing the Hong Kong Trailwalker (www.trailwalker.org.hk), a 100-kilometer race with a lot of big ups and downs. I will probably do in about 25 hours. Last time I did it in Reebok DMX10's. I liked that they were lightweight and I think the cushioning helped my knees a lot on the downhills, but I developed large blisters and lost three toenails, which was rather unpleasant (I didn't get feeling back in one toe for six months.) I'm thinking that maybe the DMX's were just too flimsy for the trail and let my feet move inside them too much. What are your suggestions for other shoes to consider this time around? Mike Luechtefeld Dallas, Texas

After spending all my life camping in the mountains of the eastern United States, I've fallen in love with the southwest Texas desert, and I'm in the process of learning about those techniques and equipment that will work in that very different environment. No trees, blazing sun, the ground too hard to set stakes, fairly constant strong winds... The first problem to solve would be creating some shade... My Integral Designs Siltarp, which works great in the forests of Virginia, is useless as a sunshade, being almost transparent. Are there any tarps out there that would be suitable for sunshade duty, or is a piece of black six-mil poly my best bet? Bill Stell Charlottesville, VA

Great Gear Guru: My hips hurt when sleeping on the ground, whether I've just humped a 60-pound pack or walked into my backyard. I currently use a Therm-a-Rest GuideLite sleeping pad. Do I need a new state-of-the-art pad, or should I just chalk it up to old age? Brad Sioux Falls, South Dakota

I'm going to be spending a year working in Kenya and need to find a sleeping bag. I need to get a synthetic bag, but I want one with mobility since I move around a lot when I sleep. I don't like the constriction of most bags. It also needs to be fairly compact. What do you suggest? Paul St. Louis, Missouri

I camp in the desert in the winter when temperatures can range from zero to 90. My main concern is the wind, which can be downright chilling but also kick up sand. I'm looking for a tent that will shed wind and also not flap like the sail of a 12-meter yacht when it tacks. I'd really like to sleep without the noise. Can you suggest a suitable three- or two-person tent, preferably something on the roomier side? Chip Cairo, Egypt

I just read your reply in reference to a question about sleeping bags for a big guy, and I have similar question. I only five feet, ten inches tall, but I have broad shoulders. I trying to find a mummy bag that is roomy enough through the shoulder area to move in. Do you have any recommendations for good but not too expensive down bags like this? Tad C. Helms Tallahassee, Florida

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

I interested in buying a quality set of boots and skis, primarily for Vermont and New England skiing. Problem is, I wear a two-centimeter orthotic insert in my right shoe that corrects a leg length problem and heavy over-pronation. Can I get this custom built into ski boots? Any other options? Also, what's your opinion on the softer boots like the Atomic Beta Ride 10.50? Are they worth the $600? What is the best ski for varying New England snow conditions (i.e. one day powder, next day ice)? Walt McMann Hden, Connecticut

I would like some advice on a permanent or removable roof rack, mainly for carrying several pairs of skis on my Isuzu Trooper. Isuzu sells a rack for around $350, but I'm sure I can find something better for the se money or even less. John Boise, Idaho

I considering buying a pair of hiking shoes for day hikes with a light load (usually my 30-pound daughter in a child carrier). I have a pair of Merrell hiking boots and tennis shoes and I find both too warm (I don't know if its just me but I find tennis shoes very warm even though I don't have a tendency to sweat). Hence, I always end up using my Teva sandals, which don't give me enough support and don't protect my feet. Can you propose a closed hiking shoe that won't make me feel like my feet are in a furnace? Thanks in advance. Guillaume Frechette Columbus, Ohio

Dr Gear Guy, please realize that you are completely indemnified from any liability as to the efficacy of your answer, but I'm wondering what gear you'd specifically recommend for a hiker who has undergone a total hip replacement and refuses to cast a deaf ear to the call of the wild? I have a pair of good trekking poles. Anything else come to mind? Keith Columbus, Ohio

My ne is George, and I a Gearaholic. I know I have a problem, but I cannot control myself. Although I have eight packs, ranging from a Gregory Denali Pro to a Mountainsmith Ghost, I have the se dilemma with all of them. Though of average build, my hips are non-existent, causing my hipbelts to slide down my waist. This problem can be very bad in winter when lugging a heavy pack and wearing slippery Gore-Tex clothes. Are there any gripping solutions that can be applied, or is there another pack that can cure my problem? George Rochester, New York

I've been looking for a lightweight, water-resistant jacket for hiking and mountain biking. I've been looking at the Patagonia Dragonfly Pullover, which is advertised as water-resistant, very light (3 oz), and compact. It is also rather expensive ($135). Is this jacket worth the money? Are there any other jackets this category that you would recommend? Chris Newark, New York

Have I got an expensive proposition! I'm planning a trip to Italy and thinking it might be the perfect time to buy a new road bike straight from the factory, say Pinarello, De Rosa, or Colnago. Are there any advantages to doing this, such as incredible savings, or seeing the bike in progress and test riding it in the mountains? Are there drawbacks, such as duties, taxes, exchange rates, warranties and language that would make this way more trouble than it's worth? Thanks for your wisdom! Bob Foster St. Louis, Missouri

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

With all the high-tech lenses out there, I'm looking for a pair or two that will provide good protection in a variety of situations. I would be using them for downhill skiing, water sports, motorcycle riding, driving, hiking, mountain biking, roller blading, etc. The three brands I considering are Revo, Oakley, and Serengeti. I was also told by someone a long time ago, that it is not a good idea to wear polarized lenses when riding a motorcycle, as they will hide oil spots on the road, causing a potential slide. Can you tell me if there is any truth to that? Tom Player Toronto, Ontario

I'm interested in buying a new kayak for touring and open-water paddling, but one that could also take a little whitewater action once in a while. What would you recommend? Jeff Midland, Michigan

I'm going overseas for approximately two years. Unfortunately, there'll be no camping opportunities the whole time. Before finding out I was off, I purchased a new tent, sleeping bag, and backpack. What's the best way to store this gear so it's as good as new when I get back? Gil Beaumont, Texas

What do you know about the "Stealth Can" and its effectiveness? From what I read, it's impenetrable to bears and seals in odors to throw animals off the scent. I like the idea of pre-empting animals from entering cp, rather than "teasing" them with food they can smell but not reach. Mark Ewing, New Jersey

Will boiling or adding chlorine dioxide to water neutralize all organic chemicals (i.e., industrial waste)? Also, should you filter water after using iodine or chlorine dioxide to purify it? Does ViralStop (from SweetWater) kill anything other than viruses? Basically, what's the simplest, lightest way of neutralizing EVERYTHING? Seyil Toronto, Ontario

My sweetie and I are going to Everest's Khumbu Icefall this December, where it's likely to be numbingly cold. I'd like to buy her a toasty parka for this trip and have homed in on Feathered Friends' Icefall and MEC's Frobisher. But will those jackets be significantly warmer than our current 550-fill REI parkas? Should I pay for the 800-fill down or Nextec Epic (apparently the best thing since somebody figured out how to shear a sheep) if I go with Feathered Friends? Or should I be looking at other parkas? Robert Fairview, Oregon

I've noticed a strange paradox in my personality. When I go out to the woods, sitting in some remote beautiful locale I often in want of one thing: a margarita. I've often theorized different devices that I could construct to make a blender but nothing ever made sense. And then I found the GSI hand-cranking Vortex Blender. While I would never take this backpacking (OK, maybe on a day trip to be fancy in front of my exhausted friends) I would definitely be interested in it for kayak camping and car camping—so long as the ice lasts. But does the thing actually work? Or is this really a doomed fantasy of mine? I'm skeptical about the amount of effort this thing would take to crunch up ice. I'd love to pop this out and be a hero. Brian McCarthy Glendale, California

Long time reader, first time questioner: I have long been a fan of liquid-fuel stoves, but recently read your advice about the difficulty in obtaining white gas products abroad ["Do they sell white gas for stoves in Europe?"]. I about to head out on a nine-month round-the-world trip, so would like to take along a reliable canister stove. Do you have any information on which canister stoves will mate with the multitude of international propane canisters that I'm likely to find? Europe and Oceania are my probable destinations. Aaron Green Bay, Wisconsin

I'm interested in testing the triathlon "waters." Can you suggest any good bikes for a beginner triathlon biker, say, for under $1,000? Gary Quito, Ecuador

Do you have any tips for taking a dog on trail? I'm taking my dog on her first trip and want to protect my gear without constantly worrying about it. Are those packs dogs wear a good idea? Will she dage the inside of my tent? Kieran Hosey Frankfort, Kentucky

I'm looking for a pair of Gore-Tex mountaineering pants that I can use snowboarding in the Alps, climbing in rainy Scotland, or cross-country skiing in Norway—all without maxing out my credit card. Any suggestions? Jakob London, United Kingdom

I recently unpacked my tent to be hit by a powerful smell of chemicals and mold, so bad that it gives me headaches and I can't sleep in the tent. Could I just wash it with some mild soap to get rid of the stink? I believe that the ses were sprayed with some sort of leakproof sealant, so I think that's why it smells. Janie Kuala Lumpur, Malaysia

I have been contemplating hiking the Appalachian Trail. Having spoken to a number of through-hikers, I'm told that many are using homemade alcohol stoves made from soda cans. Can you give me your take on alcohol stoves? Have you had any dealings with an alcohol stove known as the Trangia? Mark New York City

How do I wash the sweaty odor from my polypropylene toque? I used Wisk liquid detergent without success. The toque is clean but it still smells badly. I need help. Alexander Do Toronto, Ontario, Canada

Just wondering if you know of any companies that do any sort of maternity outdoor wear, the actual technical garb. I realize that a pregnancy only lasts so long and we already have to add to our wardrobe as it is, but it just so happens that my few biggest months will be the hiking season. I have tried on some of my other gear and think a few pieces will work, but is there a manufacturer who makes stuff that will actually let me and the baby hike comfortably? Charlotte Winnipeg, Manitoba

I have an early-nineties GT mountain bike with a titanium fre. It's still a good-looking, lightweight bike, but its rear U-brake has no real power. Are there any compatible brakes with better grip, or are there any pads with magical powers? Andreas Reno, Nevada

I've read your praise for the Yashica T4 point-and-shoot camera and was attempting to locate a refurbished unit on the web, when, lo and behold, up pops the new Yashica T4 Zoom with a Carl Zeiss Lens (28mm to 70mm). In the wilderness, I've always managed to catch more pictures than fish, and would appreciate your thoughts on a lightweight point-and-shoot for my arduous outdoor adventures. Scott Maple Valley, Washington

Why did Sno-Seal fall out of favor? I kept a pair of heavy hiking boots alive for years with some welt dressing and this stuff. Joe Midland, Texas

I'd like to buy my dad a comfortable bike for exercise and recreation. He doesn't like to be hunched over a bike because he has a temperental back. He also needs a comfortable seat. Is there anything for $800 or less? Joe Edison, New Jersey

I have been searching online for the past few hours for piece of equipment that I believe I saw in some gear magazine (the mail order kind). I will describe it: digital watch, with a compass, stopwatch, etc., and a lighter, signal mirror, and small knife blade with various other attachments. It hung from a lanyard and cost around $100.00 or so. Can you help me find a name for this product or where I might be able to order one? Thanks for the help. Bradford Hammar Charleston, West Virginia

For the second year in a row, we have just returned from our annual spring camping trip in southern Utah, and because of blowing dust, the zippers on the tent are EXTREMELY difficult to operate. Are there any methods for treating "dust-laden" zippers in the field? Also, now that we're back, we've washed the tents, sprayed silicon on the zippers—they're better, but still not like they used to be. Any suggestions? I've been told to buy some "zipper wax" to carry camping next time, but no one here seems to carry it. Thanks! Kirk Astroth Belgrade, Montana

I have a 2001 Honda Civic coupe and will be making a cross-country trip. I looking into a cargo rack to outfit my Civic but I'm not sure how much to spend and which brand to go with (Thule, Yakima, or Saris.) The rack will probably only be used for a rooftop storage bag. If you could suggest a rack model I would greatly appreciate your help. Pete Lptey Fairfax, Virginia

I just returned from Mount Rainier with a rope I had bought specifically for this trip but with the intention of using it for rock climbing. I hate to think of the number of times I saw it go under foot. None of my ropemates put a crampon into it, but I sure don't see myself taking a lead fall with it now, especially 100 feet up. But what about glacier travel? Certainly the guides on Rainier leading newbie mountaineers don't replace their ropes after every trip. Is there anything I can do to physically check the condition of my rope and feel comfortable using it for glacier travel? I truly hate to toss a rope after one trip.

I looking to buy a new tent for canoe tripping in the barrens of Canada's Northwest Territories. I expect lots of wind and rain so an expedition tent would be best. But what is an "expedition tent" anyway? Robert Guelph, Ontario

In answering the question, "What's the lightest three-person tent available?" a few weeks ago, you missed by far the lightest candidate: the Stephenson WarmLite! It can weigh as little as 3.25 pounds and has 52 square feet of space! Dave SteinerNew York

What type of bag would you recommend for climbing Denali? Down or Polarguard insulation? What specific bag would you recommend? What about as far as clothing—layers, brands, models etc.? Would you recommend a full down suit? Or a down jacket and either down pants or a shell with layers? Bob Grish Boise, Idaho

I planning a weeklong sea kayaking trip in northern Quebec. I (and my backside) would appreciate any of your thoughts on a decent portable sleeping pad. Is inflatable the way to go? And what about length? We anxiously await your deliberation. Nicholas B. Westmount, Quebec

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'm looking for an ultra-lightweight three- to four-season ski touring tent for spring in the Sierra, though it'd be nice if it could handle some winter weather also. I HATE carrying a lot of weight ski touring. Any ideas? David Hunn Long Beach, California

What gear do I need to climb K2? Just kidding! With winter fast approaching, I'm thinking about backcountry skiing again. I take avalanche safety VERY seriously and therefore take every necessary precaution. That said, accidents do happen, so I'm looking to buy an avalanche beacon just in case. I'm interested in the Tracker DTS, but how does digital technology fare in cold environments? I've also heard that earlier Tracker DTS beacons had problems with the unit switching to "receive" mode if the wearer's body pushed up against the toggle switch. Is the Ortovox F1 Focus a better, more reliable choice? Michael Vancouver, British Columbia

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 planning a three- to seven-day mountain biking trip this summer. If I'll be riding up to six hours per day, what tent, sleeping bag, and backpack will I need? As always, your advice is very welcome. Mark New York City
