After Marie picked me up at the King Street Metro, we dropped by her mother's, had lunch up by our old high school (TC Williams), then headed over to South Glebe Road. When I was a kid, we would have called this area "over by Four Mile Run, past the Potomac Yards train tracks, near the Hole."
Nothing "Hole" about it these days. There's a fancy-pants shopping center where the railroad tracks used to be.
And in one of these shopping centers, there's a nail salon.
