I'm 51 and still hiking away. When the kids were smaller it was difficult to go very far. But, now the boys are 23, 20, 18, and 13 and love the outdoors as much as I do. I've convinced them that since they're in their prime of life it's only fair that they carry heavier packs than mine. we just spent a week in the cloud peak wilderness area of the Bighorn Mts. of Wyoming. It's a fantastic area and I got by all week carrying about 10 pounds less than the rest of them. It's payback time for 15-18 years ago when I'd be carrying gear and them.
