The next San Francisco's Sunday Streets is on the Embarcadero, between Fisherman's Wharf and AT&T Park (yes, it's big!). They'll be closing off the northbound lanes to traffic, so you can walk, skate, bike, etc. Are you going?
It's Sunday, March 8 between 11 and 4 (beware of the time change - spring!)
You'll can take advantage of Pier 39 discounts for locals, and at the Exploratorium too. Sunday Streets is a "a safe, fun, car-free place for people to get out and get active in San Francisco neighborhoods." In addition to the regular fun stuff (dance performances, climbing wall, live music, free bike rentals, yoga, pilates, arts/crafts) too. Sunday Streets details and map here.
