Horses cause trail erosion, but no one is stopping horses from accessing trails. Free-range cattle grazing cause trail erosion, but no one is stopping cattle from grazing. And neither am I, dude, I am all about equal access, and right now, there isn't equal access.

What happens when FR stunts are taken down, or FR-ers are denied access to trails is that the reckless minority who are sick of it and have the balls will go built stunts anyway, ones they can put up and take down in a day. Obviously these aren't as safe or as well-built, but they don't have the opporutnitiy to do it right when other people rip them down anyway. Remember prohibition? No one stopped drinking just because it was illegal or caused liver disease. People are going to find a way to do something, so the best thing to do is give FR-ers some stunts to rip on. What is the big deal? A bridge that doesn't even touch the ground for its whole span HAS to have less of a trail impact than an actual trail on the ground, where people can skid their tires and rip up the dirt. It isn't about erosion. It is like what that other dude said about snowboarding.
