12 mile uphill - gaggerto the top of mt. wilson. you can then get some chili at the observatory and a red bull at the snack bar. Head north down the asphalt across the ridge to the tunnel of no return. take the single track to the dragon's teeth. Bring three tubes or berzerk it across the razor sharp one mile granite section like chad reed. You'll probably want to get down as fast as you can after having the red bull and chili. Watch out for the water bars at Mt. Lowe ruins, if you hit them at 60 you WILL go over the bars. this ride is way too much fun and very addictive. it should only be done twice a month to allow your stomach to recover from the chili.
Review: The Mount Wilson Toll Road is a steep, steep fireroad climb, but if you just want to ride down it it can be shuttled by driving up the ACH (Angeles Crest Highway, CA Hwy 2) to the Mount Wilson observatory.
