The route map is available online at: http://www.aidswalk.net/sanfran/eventinfo/maps.html#route
"The AIDS Walk San Francisco is happening in Golden Gate Park; Please be advised that the area will have increased pedestrian and vehicular traffic during that time. If you're planning on fast park ride, please consult the route map and plan your ride accordingly."
“I can only hope that one day rhetoric will be followed by action. This isn't rocket science, and yet too many SFPD captains can't - or won't - figure it out. Getting killed or seriously injured in a traffic crash should be taken as seriously as getting killed or seriously injured by a bullet.”
