I keep a good BOB (all the usual stuff) in an old backpack, that way if I have to walk I can carry the essentials. BOB includes 3 litres of water MRE's, gum, candy, soup, drink mix, small stove, cookset, fuel, and other foods. SAK, 550 cord, chapstick, hat, gloves, socks, tissue, hand wipes. A very basic "camping" set up and the ability to stay warm. Compact sleeping bag, FAK , trauma bag and tools are also carried.
