From Golden Gate Xpress, 22 September 2007:
People overflowed into the street and crowded around the westbound bus stop at Haight St. and Fillmore St on Friday night. They whooped and threw glow sticks in the air, dancing freely to music pumping out of the rigged bus stop and a nearby car, and green lights flashed from the tiny shelter where people usually just wait for the 6, 7, and 71 bus lines.
This impromptu rave, like the pillow fights, zombie days, and big wheel races that came before it, is an example of people in San Francisco deciding to create their own fun for free. These peaceful free-for-alls help people forget about all the stresses and serious concerns of the day and just cut loose for an exciting good time.
This rave was organized by Brent Lowteck, 25, a San Francisco native who has rigged bus stops at least five times before this. SF State alumni Leslie Carroll, 24, and Alex Oestreicher, 22, both heard about the rave on laughingsquid.com. “It shows the character of the city, that we don’t take ourselves too seriously, that we can get together and have fun at a bus stop in the Lower Haight on a Friday night,” said Oestreicher... Bus riders were also surprised at the crowd cheering for the bus as they pulled up to their stop, but none were annoyed by the ravers, one saying it’s a great thing to do on a Friday night.
The police came to the site three times before 11:00 p.m. The ravers would turn off the music, light up cigarettes, and stand around waiting for the authorities to leave. As soon as they did, the party was back on... By 11:00, the crowd was about half as large, but the remaining few kept the party going, having fun for free and clutching their brown-bagged beer bottles as they danced into the night.
