Exploratorium After Dark: Civic Hacks

From SFBC:

Be a part of The Exploratorium’s monthly After Dark series! This month’s theme will focus on how we can improve our  city’s public spaces. Play in a parade of pianos, design a miniature Market Street, and test whimsical exhibits in preparation for next year’s Market Street Prototyping Festival.

Your San Francisco Bicycle Coalition will be providing free Valet Bicycle Parking, so come park your bike with us!
