One thing I love about San Francisco is that this city will close down a street or entire part of town for almost any reason. On any given weekend throughout the summer you will find several miles of “Closed for Party” road.
This July 4th was the 2010 Filmore Jazz Festival. 12 solid blocks of people, music, food, and of course… lots of beer!
I went by and saw a few great bands playing. A super DJ working a corner was turning making a real dance party out of it.
