Photos: Bay Bike To School Challenge

Here are photos from all three weeks of the Bay Bike to School Challenge on May 9-27, capturing the joy of bicycling to school for both students and teachers of Bay Middle School and Bay High School.

Now in its fourth year, Bay Bike to School Challenge hit a major milestone in 2011 -- its students have now bicycled a total of 102,803 miles since the program began in 2008! Number of smiles? Countless!
