Youll love the hike, Jeff! Plus, its a good target=. You might even find that you like this hiking business and make it part of a year-around fitness program. Besides, if nothing else, Glacier National Park is just so spectacular that you cant help but enjoy yourself. One of the most fascinating things about the park is that there are so many remnants of past climate zones there. Bits of West Coast rain forest, Canadian boreal forest, Great Plains grasslands, all jammed together with more typical Rocky Mountain Ponderosa pine forests. Fascinating, and especially noticeable along Lake McDonald.
Anyway, I digress. Fanny packs or, to use the more dignified name, lumbar packs." There are a few pretty good ones. One is Marmots Walkabout Lumbar Pack ($65; www.marmot.com), which is designed with a mesh back panel that spreads the load around as much as possible. It holds 625 cubic inches, enough for a light jacket, gloves, a hat, and lunch. And blister kit. Two side pockets can handle your water bottlesand youre gonna need at least two quartsand a removable shoulder strap also lets you sling it over your shoulder. Marmots Highlander ($80) is a little larger at 1,000 cubic inches and has shoulder straps that take some of the weight up and over the shoulder and off the back, which can be a good thing. At that point, though, you might as well buy a small backpack.
Mountainsmith is a company that sort of defined the modern lumbar pack, and its still a big player in that small market. So take a look at its Tour Lumbar Pack ($70). It has 660 cubic inches, two zippered compartments, and side pockets for bottles. External loops and attachment points let you seriously overload it.
Now get back on that treadmill!
