Wow advertising on trails? I like riding the trails to get away from advertising and cars and all of the other stuff that goes with riding on the roads. Don't get me wrong I ride the roads too, but I don't want all that while out riding in the woods.
I guess I would not mind some sort of advertising at the start of a trail, at the trail head or something. If it does raise some money for the trails. But NO way do I want the whole length of a trail plastered with signs.
