These two hikers are doing a tremendous service. With all the turmoil in our world, it is good to see two members of the hiking community doing something decent and positive.
During my long-distance hikes, I’ve picked up some trail-side and campsite trash, but honestly admit that I ignore most of it. I’ll try to do better. Wouldn’t it be nice if all hikers packed out their own trash? That’s what hikers and campers should do. Every time. All the time.
Hats off to hikers Seth Orme and Paul Twedt.
