Knife, compass, bandana, water, lighter, (TP if the wife is along).
I don't carry my ID unless I have my day pack or I am fishing. I don't believe in having credentials along 100% of the time - it decays my sense of freedom and individualism, which are only illusions, I know, but it makes me happy to think I'm something more than a number.

I'd need to specify at camp or not. When not in camp I will have either my PFD on that includes a small first aid/ditch kit, PLB, map and compass, and knife. If away from camp hiking, a daypack is always with, that includes it's own set of similar gear, the PLB will go along as well. In camp the gear is there but not always on me.

The Marines I have seen around the world have the cleanest bodies, the filthiest minds, the highest morale, and the lowest morals of any group of animals I have ever seen. Thank God for the United States Marine Corps!

Canoe, Paddle, PFD, Toilet Paper, Compass, Map, Knife, Camera, Lighter, pack, food, multi-tool, Duct Tape, Hat... thats pretty much the things that have been on my trips 100% of the time. Other items have either been forgotten or left behind at times.
