going to market
It's one of the most highly bike-trafficked streets in SF, and one of the most un-bike-friendly! But we bike commuters go at twice daily to and from work.
I try to have conversations with other cyclists, but I'm often too afraid that any distraction might cause a collision with a pedestrian, the Muni, a taxi, a delivery vehicle, a tour bus or car door. So I stick to photography. ;-)
A tourist once asked me if it was safe to bike Market Street. My response: "There's definitely a system. And you figure it out quickly!"
