Riding Metro’s Red Line is like taking a train through a museum: There’s art all around you, in the form of designs spraypainted on the outsides of warehouses. Or at least, some people see it as art. Now that the Metropolitan Branch Trail has brought more eyes to the area than just those safely sliding by in a rail car, the city sees those warehouses as frustrating enforcement zones. It’s devoted significant energy—whitewashing every few weeks, commissioning murals—to ward off taggers. In her forthcoming documentary, The Red Line D.C. Project, discussed at tonight’s Pink Line Project-hosted event, Georgetown graduate student Saaret Yoseph investigates the stories behind the Red Line’s now-famous graffiti, asking commuters, is it blight or public art? Salon Contra: Red Line D.C. begins at 7 p.m. Free.
