I had just stepped out of a building across the street from this group and started to head in the opposite direction from where they were looking. At the last moment I had the urge to photograph the group and as I turned to look at them I saw the Park Ranger starting to give some directions.
All I heard, as I lifted my camera to my eye, was "after you go past the Provost Marshal's office," and that was it. I was in a photo zone and concentrated on getting this quick image while trying to include both the group and the Provost Marshal's office because of what I had heard. I only had time to point, line up what I wanted and shoot, and let the camera do the rest.
I think I got I wanted... :-)
