This year’s Halloween Critical Mass was as awesome as always. A few thousand (my guess) people showed up in costumes and lights and (of course) political motifs. After many rides over many years in San Francisco, and a few scary, but important, rides in Manhattan, the SF Halloween Mass is one event I’ll keep showing up to year after year. In fact, it sounds like this year it was the main Halloween event in the city!

There’s a great video made by Streetfilms and some wonderful pictures posted on the sfwiggle blog. Found via a Bike Blog NYC post. The Streetfilms‘ video is below.
