I keep a day pack. I can remember some of it; some of it I have to do an inventory of my hunting day pack. And it took years of experience to come up with the contents. I keep my hunting stuff permanently in the day pack, so that's the reason for the inventory. Then I either keep, update like batteries, or add to it.

What do I take hunting? It's in my hunting day pack. I just have to remember to take my day pack.
