Some idiot is posting a 12 x 12 sign on the Tunnel Trail head everyday now. I know its being posted every day about 6:15am. It says attention downhill mtn bikers You are ruining this trail for everyone It goes on a few more sentences but I tore it down before I read it all. It was anti biking and very political. I called the Park Rangers and they seemed sympathetic to the poster. Public National Parks are not the place for posting your personal opinions about anything. So be forewarned. Theres a nutbag taking the time to manufacture the signs, drive all the way up Gibraltar and hang them. The next step will probably be sabotaging the trail. That was happening last year when you would turn a sharp corner only to find a nice pile or rocks and branches just waiting to catch your front tire. Just in case you are the nutbag posting these signs, get a life.
