Tonight: two ways to have fun for free

Brave New World's porch-front production of To Kill a Mockingbird. — Brave New World's porch-front production of To Kill a Mockingbird in 2005.

If you’ve never been to an outdoor show by the Brave New World Repertory Theater, you’re missing out on one of those only-in-Brooklyn nights—the plays are staged on the porch of a house on Westminster Road in Ditmas Park, and the audience sits in lawn chairs in the street. Tonight’s show is Carson McCuller’s The Member of the Wedding, a coming of age story about a 12-year-old tomboy set in midcentury Georgia. There’s another performance next week in Red Hook as well. 303 Westminster, between Beverley and Cortelyou, 7 to 9 (but get there by 6:30 to get a seat.) Also: Wednesday, August 12, Cabrini Green Urban Meadow, on the corner of President and Van Brunt streets.

Also tonight: First Thursdays in Dumbo, when galleries are open from 5:30 to 8:30p.m. on the first Thursday of the month, with special receptions (generally: free wine) and various festivities at local restaurants and bars. Here’s the full gallery list.
