I biked up to the top of the radio towers above the "Hollywood" sign. You're not supposed to bike up there, because all the stupid horse riders complain. Those damn horses do more damage to the trails than mountain bikes do. The whole trail is filled with horse $hit. It's impossible not to step on it or bike over it. Instead of dirt, the trail is made of horse crap. That's how bad the hiking trails are up there. We need to band together to prevent horses on our beautiful trails. Otherwise, you'll probably be stepping on crap your entire hike.
