I love to photograph Middle Bridge in Woodstock in the evening after the sun has gone down and there is still some light in the sky. I use a flashlight to illuminate the dark bridge. One night while there with a group from one of my workshops a police officer stopped by to see what we were doing. I told him about lighting the bridge and how it cool it looks when we photograph car tail lights during our long exposures. He offered to drive through with his blue lights turned one. It made for a quite a shot!
