A really great book to read, too, is "98.6 degrees, the art of keeping your *ss alive"
Awesome survival info, much different than the 100,000 other survival books that are all pretty much the same! Goes into lots of info on survival pack, (such as to cover everything with bright tape), how to help resuers find you (such as not only telling people where you wil be & exactly when you will return, but also things like placing a shoeprint on a sheet of aluminum foil and writing your anme on it & leaving it visible in your windshield so rescuers know which tracks are yours), how to collect water (such as a thin, flexible tubing for a straw to get into crevices and how a solar still won;t make more water than you sweat and loe thru breathing) and a bunch of really great info on basically keeping your temp at 98.6 so you don't die of hypo/hyperhermia, which is the number 1 killer of people lost in the woods.
