I never reported this, but since I found this website, thought I would in case anyone else may have reported something around the same time in Florida.

I was out doing my daily walk in the evening on Halloween night in my neighborhood.  I was almost home and finished with my walk when I happened to look up and suddenly saw a triangle shaped object with 3 lights on the bottom (in each corner)- absolutely no sound.  I just stood there not believing what I was seeing.  I had noticed some kids out trick or treating earlier and I quickly looked around to see if anyone was out but there was nobody at that time.  I looked back up and I thought it had gone behind a cloud (I think the only one in the sky because it was a clear evening), but it was gone.  I ran to the house to tell my husband and some friends and we went outside to look but never saw anything else.
