For the outdoor people, any good books on how to survive in the wilderness. For example what you can eat?

Q) I live in Cal. and I am always doing something outside, in the mounatains, and so on. I love being outdoors, but I do take risks...I know there are some really cool books and websites with info, but I always like to hear what other people have found. I like old books too. For example the books that tell you how to keep bees, and how to build a log cabin.

A) there is a board game called worst case scenario all of the stuff is true
