My second favourite movie is The Exorcist. One of the must-sees during my trip to Washington, DC was the staircase featured so prominently in the movie. I descended its 75 steps–three sets stacked on top of each other in groups of 25, separated by a small landing–and read the commemorative plaque at the lower level. I then climbed the staircase. Mark and I sat on the concrete clearing at the top of the stairs on Prospect Street and spotted two groups of people also making the same pilgrimage.
