crowd at Dolores Park for Red Bull soap box races

This weekend there was a soap box race hosted by Red Bull at Dolores Park. the racecourse was the really steep hill (one of my favorites!) on Dolores between the South end of the park and the couple blocks further south. It was a pretty goofy event but there were tons of people there (as you can see here). They estimated 60,000 to 70,000 people were there.
