Mt. Diablo is a beautiful state park in the east San Francisco Bay. There are a large number of people that like to enjoy the park by bicycle and by automobile. Unfortunately, the roads in the park are narrow and there are many blind corners. This petition is to add road signs in the park to warn visitors not to pass traffic on blind turns. Our hope is that this will raise awareness to the danger of head on collisions. Please sign this petition to help keep the park safe for both cyclists and automobiles.
