If you haven't been, its basically a large mob of bicycle vigilantes taking over streets, intersections, and forcing 'cagers' to take a few minutes to relax in mindfulness. The mob goes where the mob goes.
We'll meet up at the beginning of Market Street inside Justin Herman Plaza on the circular stairs at 5:15pm. The mob leaves around 5:30 so try to get there a bit early. I'm riding a maroon Fuji road bike with a white rear tire and black front tire. Give me a call if you have trouble finding us: 415-849-2-four-four-5
