This was the Girlz Gone Riding annual Rocktober event, held for the first time at Castaic Lake. As well as multiple rides, skills clinics, vendor booths, bike demos, etc, it included a CORBA membership drive, easily besting last year's new memberships and renewals.
Thanks to Jesse Ettinger, Graham Martin and Scott Mabbutt for taking these photos and sharing them, and to Stephanie Wolf for for organizing the photographers.
