I agree - the crappy attitude of some makes a really bad impression. I got into mountain bikes early on, and at first, there were a lot of conflicts - mountain bikes buzzing hikers, not slowing down near horses, same type of stuff.
The mtb people figured it out, internally started policing. Now? By and large, no problems. There are areas that are hiker only, a couple of trails locally that are bike only, direction controlled trails, and in some places, closed to bikes on, say, Saturday, open Sunday, or odd/even numbered days, etc etc etc.
IE, the bikes worked with the "tree huggers" and came up with a reasonable compromise. It CAN work, but. ....ahhhh who knows.
I like how dumb mtn claims that working with other groups won't work, he's been doing it that way for years and it did not work.
Ok. I agree, we've lost a lot in the past twenty years. I agree, a different tactic/angle is probably wise. I agree, his efforts were not rewarded.
But......go ride closed land? Really? Ugh. Idiot.
