Wow! I'm glad I checked this thread. Great suggestions from everyone. I also watch Les Stroud whenever Survivorman is on. Will be getting his book and the others mentioned by Ed.

I'm doing research for a book about survival after a doomsday scenerio, and up until now, I've been scrounging around for odd bits of info.
Don't want to hijack, but I'm looking for any tested urban survival techniques and general detection avoidance in rural and city neighborhoods. Any additional info is well appreciated from anyone.
