It was supposed to rain, which probably kept some people away, but the day ended up being sunny and a little cool. There was lots of publicity on this 100th running of the Bay to Breakers that non registered participants would be removed from the course and that no alcohol would be allowed and that definitely reduced the numbers in the party crowd - but there were still thousands of unregistered party people trailing at the end of the 55,000 registered runners. The threat was an idle one, just has it has been in past years when they have tried to stop the alcohol, although the ban on floats certainly took the some of the creative fun out of the event.
Nudity continues to decline on this event, but not due to any hassle from police and officials. I talked to one Bare to Breakers member who admitted that their group was smaller this year. The party in the panhandle of Golden Gate Park, which caused part of the supposed crackdown still happened, but you could actually move around there this year!
An app was released for the I-phone and Droid that gave locations of liquor stores on the route, so creative people found creative solutions and people who wanted to be were pretty happy by the time they got to Golden Gate Park!
