i have almost every survival book ever written. most center on how to survive a few nights in the woods when you are lost, some more on the shtf. all have something useful, you do need more than one. "how to survive the end of the world as we know it" by rawles is very good, as is "when all hell breaks loose" by lundin. the deyo book is great, lots of lists.
i definately agree that being on the land NOW learning self sufficiency is much better than most arm chair survivalists who live in the big cities plans to "escape"!
