The commercial stretch of Myrtle Avenue near Ft. Greene Park is populated by businesses that seem to be trying to one-up each other with exuberant, punny names. There's the Farmer in the Deli and Gnarly Vines. Buff Patty is not a Crossfit gym for women, but a Jamaican restaurant and bakery. And now, there's a storefront with glittering gold tinsel in the windows and an awning that's hard to miss. It says "Gangstas Making Astronomical Community Changes Inc."—or GMACC. Hear from its founder, Shanduke McPhatter.
