Spreading people out to relieve trail congestion will only work in the short term. From what I can tell is seems that adding easier access does not equal trail maintenance. Rather it appears to mean adding huge parking lots, garbage cans, cars, more horses, fee boxes, dog shit and tons of clueless people who've never heard of LNT. Better to just keep that crowd on the land they've already discovered because they're going to wreck it wherever they go. Eventually we'll run out of places to disperse them to. Then what?
Yes, It's way past time for the big gear makers and the giant corps that have made billions off the surge of new outdoor enthusiasts get in on the conservation, preservation and restoration act in a way that is more than just fodder for their monthly marketing campaigns. I'm not aware of anyone in the industry that's pushing something similar to Dingell/Johnson or Pittman/Robertson. If you want to affect change you'd be much better served by lobbying the corps that lobby congress. If you can get people to stop giving their money to the multi billion dollar companies that pay off our legislatures you might get someone to pay attention. Good luck with that.
