Goooooooooooood morning Noo
Well, I have two answers to your first question. The first set is what i would LIKE to have, the second set is what I would be more likely to have on me when it happened, as if I were able to choose what to take I could likely have chosen not to be stranded :p
1a. First aid kit, Zippo/fluid, hunting knife.
1b. Candy bar, purse filled with completely useless junk/trash, book.
2. Internet, books, internet, cigarettes (yeah I know), internet, and lastly, internet.
3. No internet (bet you didn't see that coming :p), lack of companionship, and the utter loss of the disposable, have-it-your-way-and-have-it-right-now society we've built ourselves.
Good luck on your project :)
