Sunday Streets in the Mission again. The most fun thing ever. Thousands of people turned out.This thing is a rolling P. A. system. I never did see this guy dismount, must be some feat.He was rollin’ up 24th, playing tunes. Accomplished pianist, he is, but how does he steer? Maybe F sharp for right and D flat for left.“That’s a rather odd bicycle you’ve got there mate.” “Well at least I don’t have to water mine.”Don’t get on the wrong side of this biker. In fact, don’t make eye contact.A wheelie that was sustained for like 50 meters. Just thought I’d go metric for the Canadians out there.
