On really cloudy nights here there are strange lights in the sky. It can really take you by suprize if you aren't expecting anything to be there. There are four of them and the move wildly in circles across the clouds, meet in the middle to form one giant light, and then continue over again in the same pattern. There is of course an explination for the lights. The University of Rochester's medical school is part of Strong Hospital which happens to have four helipads complete with giant search/spot light things. The lights on the clouds were from those, but I still like to look up every once in awhile and let my imagination invent me another explination.
