SF Chronicle and Laughing Squid informed San Francisco's quirky event enthusiasts that unless the organizers obtain a permit, SFPD will be issuing tickets to anyone participating in Sunday's Bring Your Own Big Wheel race. Lots of people are upset about this. The race will still go on, but the BYOBW organizers are urging people not to bring alcohol to the event, to use the porta-potties, and to clean up their messes. Check out video footage from last year's event. UPDATE: The police will be barricading Vermont St.
