Boulder Outdoor Survival School, Boulder, Colo.

With a survival school lineage going back to 1968, BOSS puts a total emphasis on living in the wilderness with a minimum amount of modern technology; i.e., making a fire using a sticks and tinder; sleeping on the ground. BOSS instructs students how to adapt methods of older cultures (the Anasazi and Fremont) when living on arid lands for extended periods of time is the only choice. Most students must pass minimal physical requirements. The 28-day survival course in the Utah wilderness will push you beyond your known limits in the desert (you'll probably cry a few times, too), but you'll be a changed person when you make it.
