Photo: Between heats at the Bring Your Own Big Wheel races

For the last six or seven years, the Bring Your Own Big Wheel races (warning: embedded music) have been a San Francisco Easter tradition, started by local Jon Brumit. In 2007, when this picture was taken, a medium-sized event tolerated by the locals grew roughly tenfold, flooding the famous street with between 200 and 300 participants, and many, many more spectators. Complaints about the noise and about $250 of damage caused to the street's hedges has caused the city to clamp down on the race being held on Lombard in the future, so alternate locations are being looked into.

Here, racers climb back up Lombard after a heat. In the background is Coit Tower atop Telegraph Hill.
