The store I rented the OT movies from was originally a West Coast Video that opened near my neighborhood in the early nineties. It became a Forbes and then a Potomac Video before moving next to a smaller space in an adjacent strip mall and then closing.
Potomac video had several locations around the DC area. By complete coincidence, I now live only a few blocks from the last remaining location.
The last time I saw a Star Wars movie on the big screen (RotS) was at the historic, single-screen Uptown in DC. It was the only theater in the area showing Star Wars on May 25, 1977.
They converted to digital in 2010. For 3D movies they usually alternate 2D and 3D showtimes. I'll probably end up seeing Episode VII there at the midnight opening, unless that particular screening is in 3D.
