The first 2010 Sunday Streets 
in the Mission drew huge crowds for five hours yesterday, with countless young kids learning to ride and enjoying the car-free space. Organizers estimated approximately 25,000 people came out, though I could have been convinced attendance was higher given the dense foot and bicycle traffic along the route.
Unlike last year, Valencia Street was nearly as crowded with people as 24th Street, making it difficult at times to ride a bicycle. This year organizers added Harrison Street between 16th and 26th Streets as the newest piece of the route. Susan King, primary Sunday Streets organizer at Livable City, said Harrison was added because they needed more room for the crowds, especially cyclists.
As such, Harrison was clearly the route for those who wanted to pick up some speed on their bicycles, with a long descent toward 16th Street and plenty of room to ride relaxed. Check out more of my photos  below and be sure to come out July 11th if you weren't able to attend this month.

The death of the mini-van began with this bike.
He's already a little stud with his Radio Flyer.
Deep picked up a few passengers.

Some of the wonderful volunteers keeping an eye on vehicular traffic.
Doesn't this girl bear a strong resemblance to this girl ? Graduating to a new bike a year later?

Surprised he wasn't juggling too.
