The 36 best things to do in D.C. this weekend and next week

The final weekend of the National Cherry Blossom Festival brings a blizzard of events, including a parade on Constitution Avenue NW; a two-day street festival on Pennsylvania Avenue NW; and a day of music, art and games in Franklin Park. But events are popping up all over the region, including an exhibit on state flowers at the U.S. Botanic Garden, a walk and bike ride that lead to a tulip festival along the George Washington Memorial Parkway, a flower-centric tour of Georgetown, and two early Earth Day celebrations. Music fills the air at Mosh Madness, a festival of basketball and punk, and the center of Dupont Circle. Artists lead tours of pop-up artworks in Adams Morgan, and a new exhibition at the National Gallery of Art. Pop-up markets celebrate local makers in Ballston, Navy Yard and Columbia Heights, while Rhizome encourages the community to trade their old records, VHS tapes and DVDs for something new.
