The sun is setting earlier and D.C.’s oppressive humidity appears to be making a rushed exit: All signs point to summer ending, but not before a favorite local tradition takes over Penn Quarter. Shakespeare Theatre Company’s Free For All marks its 25th anniversary with a remount of its 2012 production of A Midsummer Night’s Dream, and it’s just the right show to extend the feeling of seasonal relaxation for a few more weeks. STC has only staged Midsummer as part of the Free For All once before, in 2005 when the productions still took place at Carter Barron Amphitheatre and audiences and actors had to contend with the elements just as the Bard’s original actors did. Now, in swanky, air-conditioned Sidney Harman Hall, audiences will get a different experience than they did a decade ago, but with just as many laughs: Jokes about donkeys and bottoms are never not funny. The play runs Sept. 1 to Sept. 13 at Sidney Harman Hall, 610 F St. NW. Free. (202) 547-1122. shakespearetheatre.org.
