I have new neighbors who just moved in to a house across the street from me around 3 weeks ago. A few days ago I saw something sitting on the roof of the house and my first thought was that they were going to have a new roof put on the house. Later that day, I got a better look and saw this unusual row of characters sitting on the roof line of the house.
Later again, I noticed that this group had joined the "roof-sitters" to play around in the front yard of the home. I would say that these people really enjoy decorating for the Halloween season. I wonder what they will do at Christmas time.
