Smithsonian Folklife Festival
A huge festival that goes on every year on the mall in Washington, DC.
Digital Capital Week
This one is new to me, it's a conference really. But it looks exciting so I'm going to check it out.
Columbia Festival of the Arts
Another great festival celebrating all the arts in Columbia, Maryland.
This is also mammoth in size in the heart of the arts district in Baltimore, Maryland.
Capital Fringe Festival
A lot of great theater shows all across this city of DC and music and such.
