On our family reunion I had the opportunity to teach some teenager (and under) kids how to build a debris shelter. They took to it with gusto, and although we ran out of time, it was beginning to take a nice shape. They started out with too short a ridge pole, though, so we named it the Hobbit Hut.

I guess the next generation isn't lost, yet.
