We have a large trail system called Brown Mountain Trails. Miles and miles of trails accessible to mountain bikes. Most around here quit using them because of the damage done by bikes! Even the bikers are not using them because of super deep ruts.. As far as bikes in Wilderness areas keep them out, or let every wheeled vehicle in,bike riders should get no special privileges nor should anyone else! All who use the trail system should help maintain the trails or pizz off. My two cents
