Surf's up!
Winter storms frequently bring a northwest swell that makes it through the south side of the Golden Gate. Surfers like to ride the waves just off Fort Point, on the southern end of the bridge. Photographers like me love the composition...check out the shadow of the north tower on the Marin Headlands!

Of course, the big waves today were at Mavericks (www.maverickssurf.com) The waves for the contest there were running 30 feet or so.
