Fans are descending upon San Francisco for today's Giants World Series parade, which you can watch live here, starting at 11 a.m. Here are some images of the action before the parade. Looks like people are getting an early start on the day-long revelry.

Market Street will be closed to traffic for duration of parade. Drivers should avoid Mission Street and Civic Center for most of the day. Mission Street is also closed to vehicular traffic from Embarcadero to South Van Ness Avenue.
