Found!

As I was walking out the door I noticed that some of the sage's leaves were turning yellow. I decided to see if this was the case on both bushes. I walked around, looked down, and was greeted with a suprise. I found the skull that blew off the door during the wind a couple of days before Halloween.

I though I looked everywhere. Next year I think I am going to add some weight so we don't have this situation again.
