I'd trust your son bugging out more than 95% of the bug out keyboard ninjas around here...
I'm not a terminology guru. For oh, I don't know - 25 years, I've referred to the pack in my truck as a "get home pack"...My decision to make one didn't come solely from my tinfoil beanie. It came from being legitimately stuck in the middle of nowhere with nothing but myself, an emergency road kit, two packs of Camels, a lighter, a one-hitter with some really good Panama Red and a half a cup of coffee. I made it to safety - drenched, shivering and lucky, (happened to wander onto a farm). Couldn't even smoke - my lighter got soaked after the first hour. Since then, I've always had a little something in my car to get me home if I need it. I won't bore you with the details, but it parallels Timber's son's kit more or less. In the winter I add snowshoes and in the summer extra hiking boots. I also am a believer in fire kits. I have spare lighters, but a blastmatch, waterproof matches and some homemade wetfire type tinder. I've also found those topographical map books pretty handy. Other than that, my objective is to get my ass home or to safety - not fight a war or be the coolest mall ninja on the block....
