As many times as I can I mountain bike up a local mountain. Three years ago I was riding up and this old guy was coming down rolling a furniture dolly with three or four decent sized rounds.On his back he had an old pack with two or three hand saws and some wood in the pack. During a lengthy conversation he told me that he had permission to take firewood off the mountain. He cuts it all by hand and carries it off the mountain by cart... every day. I still see him when I ride up and he's still cutting and hauling, though I have noticed his loads have decreased somewhat. I guess that's to be expected when you are 93!
