Mountain biking is one of the most destructive activities ever allowed in natural areas, and not something that a school or university should be lending its name to or promoting. It accelerates erosion, creates V-shaped ruts, kills small animals and plants, drives wildlife and other trail users out of the area and (worst of all) teaches kids that rough treatment of nature is okay. It’s not!
