There is always the need to do something so people find themselves doing the wrong thing. It's really tough to beat those feelings of helplessness, so you "go for help".

One of if not the primary kits I have is the one in my car. But I'd also have my GPS (long trip I'd both of them) which I could use to backtrack if I decided I had to walk out. More likely though, I set up camp, get a fire going, then have a cup of tea and dinner. It's an adventure, not an emergency. I'd check the GPS and maps to see where I was in relation to major roads. Then if I deided to walk out I'd orienteer my way out using the GPS bread crumb trail and logging road as a guide. I would not be busting brush or trying to follow and overgrowth laden stream. You are much more likely to be found walking on a logging road than following a stream to the Pacific.

Good point about the 406 MHz PLB. Relatively speaking, it's cheap insurance.
