I' ve been caught without a couple of times, so now I always carry a backpack with: a lunch, a spare knife, calls, a rope, spare compass, tp, spare matches, a couple of plastic bags, a pair of socks, and a flashlight with spare batteries. There is enough room left over for me to roll up my heavy coat, extra gloves, and warm hat, so' s I don' t overheat on my way to the blind.
