It's Artomatic season on DC again. It's a great event if you have never been. Lots of painting, sculpture, mixed media, photography, ceramics, glass. 9 floors I think, music, poetry...and it's free. But only through June 15.
Warning if you are traveling from NW DC, the directions are wrong. Turn right on M St. NW, not left. Follow the directions from the 14th Street Bridge.
