The DC Preservation League is holding its first Instameet on Sunday, July 16, to explore the mid-century modern paradise of Southwest DC. Beginning at Arena Stage, the group will tour part of the neighborhood and photograph housing that includes the aluminum domes of River Park and one of I.M. Pei’s lesser known apartments. Afterwards we will cool off at Cantina Marina (cash bar) and enjoy free snacks. The tour will start at 5 pm at Arena Stage entrance (two blocks from Waterfront Metro). Sign up here.
