Jerky. asap after shtf go out and get as much game as you can haul back and salt/dry out or turn into jerky. It will keep for years when stored in a cool dry place in nothing more than a paper sack. greasy critters like raccoon, opossum and bear don't make good jerky. Not saying it can't be done, but you need to get the fat off of the meat or it will go rancid before the cured meat goes bad.
