Well, what else? Survival!
no, seriously. hmmmm. *thinks* some sort of energy bars, because they keep forever. Knife is good, so's flashlight. uhm . . . err . . .
survival for *what*? For my car crashing? For my *bike* crashing?
Okay, now I remember why I don't have a survival kit - because any place I'd be that I could possibly use it, I wouldn't have it :P
well that was a useless answer. Guess I'll lob off a reply anyway ;)
