Perfectly virgin wilderness isn't very much fun to me. I like finding sparse, old stuff.

Found a very old .30-30 casing up on the tundra in Rocky Mountain National Park once.

I've been hiking a turn-of-the (last) century cattle ranch that's now a wildlife area. There's a book written about those who settled it and there is lots of their decaying work on the land left to see.

One of my hobbies is finding old (preferably military) airplane crash sites out in the woods. Lots to learn and think about with those.....
