I like this HB. I, as some others do as well, pick up trash when out there - either on the way out or on the way back - since hitting the trails is first priority. I do this no matter what trail system I'm riding. It is odd that cyclists leave they're energy bar and gel packages just laying around. Also, I have brought back tubes, chains, broken brake parts, seat (Yes! Once I brought back a seat!). You would think the very people who benefit from the great trail systems out there would "bring it back."
I don't think the fisherman take Cliff Bars and GU out to go fishing, but could happen.
Pay forward is a good thing.
