When it was over I started riding home, not that easy. Most people were walking and they filled the streets, curb to curb. I couldn't really get up any speed until south of the Ferry Building, but the crowds were mellow and full of children.
Once, when I stopped to secure my tripod, my cleat wouldn't release from the pedal and I had to hang on to a car, as I fell helplessly to that side. It was terrible. I thought I'd have to unlace and remove my shoe to get going again, but it finally popped out. I didn't clip in again the rest of the way and not sure why it happened. It did give me a laugh once it was over.
