So lots of good information and dialogue in this thread - however, I'd like to hijack the topic slightly. I have been interested in taking some of these touted wilderness survival schools to hone my emergency skills. I found one that is run by a retired special forces operative (alleged) in the Hudson Valley in NY state.

I was wondering if anyone has attended any classes like this. What did you find beneficial? Any particular class you would recommend?
