my teenage spirit says the same thing the_dude said. my 'oh golly i hope i look sophiscated' side says :
1) a super pc. 2 terabyte harddran..yadayada, thousand of books
2) a few regular books on how to construct electricity
3) a large cloth sack full of ropse, duct tape (in case of nuclear war!), 2 machates and four blade sharperning stone thingies
4) a book on species of venimous animals
5) a water purifer
oh
and tobasco..... a lifetime supply.
