Sunday Streets began in Colombia (the event is known there as Ciclovía, or "bike path"). It's a weekly effort to replace car-choked urban streets with biking and walking avenues - and a fantastically large block party atmosphere. The event is free to the public, and it's a great way to get some exercise, so get out there! All along Embarcadero, from Fisherman's Wharf to Mariposa Street (south of AT&T park) will be cordoned off for biking, walking, and all manner of community-driven events.

Sponsors include the Exploratorium and the California Academy of Sciences, so you can get your science fix while you're there. In addition to a tent full of interactive exhibits, the Exploratorium will also be showing off the work in progress on the new facility between Piers 15 and 17. The new Observatory Workshop at Pier 3 will also be open to the public.

If you can't make it this weekend, there will be several other Sunday Streets this year, so check out their website for dates and more information.
