I've tried to plan my gear kits around the idea that I may run into another person that may need help or can provide help, or just good company.
Interesting philosophy, and one that runs counter to much of what you'll see discussed here. A lot of people, myself included, prefer solitude while hiking or hunting, and concentrate more on how to avoid strangers. So while I will make provisions for supplying an under-equipped buddy, I'm not going to go out of my way to approach a stranger unless they are obviously in distress. Of course, if someone asks me for help they'll likely get it.
