I have just returned from a two week trip to a remote location (i.e.s I did not have internet) and used the occasion to consume some of my stockpiled rations - some with best buy dates as far back as 2006.

Beef or turkey jerky is practically immortal. If King Tut had been buried with Costco jerky, we would relish it today. Tanka bars were equally as good. Lara bars, a very good snack within their best buy range, showed their age, but were consumed with no problem. Clif bars were OK.

Car storage is an extreme environment. keep food out of the sun, stock normal stuff you like to eat,and recycle and restock periodically.
