SF Appeal reports that a sobriety checkpoint will go up in San Francisco this weekend. "The SFPD, along with the California Highway Patrol, U.S. Park Police and members of the San Francisco Community College District Police, will be holding a sobriety checkpoint this Saturday, August 7 from 8:15 a.m. to 3 a.m. on Sunday." Where will it be, exactly? We have no idea. Just make sure to call a cab if you get smashed over the weekend.
