I guess I shouldn't be surprised that a version of the Army's basic survival manual is on-line, but I found it interesting anyway. Especially fun was Chapter 8: Food Procurement.
Food aversion would be my #1 impediment to surviving outdoors. I get naseous just looking at bugs (which is why I think the Survivor-like shows are stupid... 90% of it is just food aversion of one form or another). Still, I have a talent for closing my eyes and doing what has to be done, so maybe I would make it.
