At 6, I was operating my train towards Jamaica, NY and had just passed the Broadway Junction (East NY) hub midway through the trip. A few minutes later, passing through an area of old low rise buildings, I saw half a rainbow basically arcing over JFK airport. (There were some dark clouds behind it, and some even darker ones down on the horizon. Looked good to make sure they weren't giant waves, or something).
Thought that was funny for "the end".
