For the past several years, the street is closed for a day long festival.
This Saturday, Sept 17, 2001;
On H St NE from 8th to 14th St.
Very family friendly, and a different way to enjoy the community.
It usually gets pretty crowded, and it shouldn't be that wonderful muggy DC September, it should be pleasant.
For ful details, check out their site http://www.hstreet.org/
Enjoy the party, come back in the evening for more fun
