I agree with having certain small essentials on your person at all times. I was once caught out overnight without my pack and it was a sobering reminder. On longer expeditions, I was frequently glad to have a knife and compass around my neck even when dropping my pack “just for a minute” to make a quick dash into the woods or around camp.

Your pack can contain all the cool stuff in the world, but if your don’t have it on you or you leave it in the car, it’s no good.
