Thanks, Pete.
I wasn't planning to shoot the rainbow. I had gone to shoot the train, and a light sprinkle had just passed. The rainbow appeared, and I just finished the shot, and I could hear the train 'a coming.....30 minutes of waiting, and nothing was going on, then in 5 min, all this happened.
No, it's a scene from a movie signed by the actors.
Due to its proximity to NYC (100 miles north) quite a few actors and artists escape to that area for the privacy.
