Sunday Streets met with a Rock the Bike event at Ocean Beach on Sunday. Some sort of amplifier was attached to bikes, then said listening device was powered by the magic of pedal power. Many revelers from Sunday Streets (an event that's quickly turning into more of a cycling event, rather than a pedestrian-friendly one) stopped by to enjoy the music and dancing

Here are some shots from Sunday Streets and the makeshift stage at Great Highway. Enjoy.

Also, the next Sunday Streets will be on September 6, 10 a.m.-2 p.m., Great Highway Route that connects Golden Gate Park to the San Francisco Zoo, along Ocean Beach.
