first question is what do you expect to survive?.just somewhat lost and a nite in the woods or a fall and a busted leg?
next a survival kit is not a kit bag that you would dip into for matches or cord but something that would remained sealed and put away until really needed.i assume your in Up State NY which i know well so i would say think,fire-food-shelter.
the photo is a copy of the kit i made in Scouts when i lived in NY in the 50's,some of the stuff is from that kit.i show it just as a starting point.the matches and fire lighters are the main items,everything else is gravy,
