FRIDAY

GET PUMPED UP: It’s the closing weekend for the Corcoran’s Pump Me Up: D.C. Subculture of the 1980s exhibit, so take a chance to go see it.

The ball will take place at Arch Square (803 7th Street NW); creative black tie attire. 7:00 p.m., $100.

SATURDAY

CHERRY BLOSSOMS: Those temperamental little blossoms will finally be in bloom this weekend, and it’ll be the perfect weather for a nice little stroll around the Tidal Basin.

MEET MARKET: Over 40 local vendors will gather at 15th and P Streets NW starting at 11 a.m. for the first Meet Market of the year, a weekly celebration local businesses, artists and designers.

PILLOW FIGHT: If you’re already down by the National Mall to catch the cherry blossoms, why not pick a fight? A pillow fight, that is. Yes, it’s once again International Pillow Fight Day, and folks will be gearing up for battle at 3 p.m. on the grounds of the Washington Monument. A few rules: no Down pillows, don’t wear glasses, don’t hit people with cameras, and don’t swing with all your might.
