Winston Groom’s ‘Aviators’

“Forrest Gump” author Winston Groom’s latest book, “The Aviators,” came out Nov. 5, and the author himself is dropping by the Roll Call Book Club on Friday to discuss it and sign his books at CQ Roll Call, 77 K St. NE at 6 p.m. For this nonfiction book, he tells the story of the early years of aviation, focusing on how Eddie Rickenbacker, Jimmy Doolittle and Charles Lindbergh helped shape things. The event is sold out, but keep checking Eventbrite’s listing, as some folks have had to beg off, leaving a couple spots here and there for the taking.

Mothers, Lock Up Your Sons

The Union Market Drive-In wraps up its fall Encore Series season Friday night with a screening of “Bridesmaids,” which was chosen by patrons via social media.

As Union Market says on its website, the film is “not recommended for children.” Hey, they might as well know what life has in store, no? Free. Gates open at 6 p.m., show starts at 7:30 p.m.
