From SFBC:
Celebrate biking in the city with the SF Bicycle Coalition with Bike Happy Hours. We've reclaimed the idea of Happy Hours to celebrate biking in San Francisco and we're throwing a streetside party every Thursday in July, handing out treats, pumping up tires and offering special local deals for SF Bicycle Coalition members. Want to be part of the Happy Hours as a Bicycle Ambassador and be the reason for smiles on the faces of your fellow bicycle riders? Email Tessa@sfbike.org if you're a trained Bicycle Ambassador and want to sign up to volunteer.
