I can't speak for WhinoCaballo but I've noticed a real effort down here in that regard. Of course you always have some dumb rednecks that'll just throw there trash out on the trail but I'm seeing more folks picking up after themselves. Along the banks of the Pearl River here in central mississppi there are a lot of sand bars. You can reach most of them by 4 wheeler or truck trail and the locals have placed 55 gallon drums out there to collect trash. Surprisingly, everybody uses them!
