Come to our July 15 program at the George Washington National Masonic Memorial in Alexandria for two great shows.   From 7 - 8 PM we will have access to the observation deck where you can see fantastic views of northern Virginia and the D.C. skyline.  Then stay for our program which will show a number of vintage vignettes from 1980s railroading in Northern Virginia, including the now vanished Potomac Yard.
