Remnants of a Mystery

Well, I'm just mystified. This is a vacant field across the creek from where I walk Rascal every day. I always look over that way because I sometimes see deer. I know what it looks like, I look at it everyday. It was probably on the third of May I looked over that way and I saw this pole that isn't usually there and ribbons were fluttering in the stiff breeze. Someone had a maypole dance there, but who? If you notice the grass is in circles around it. I drove over around that area and sure enough, there are circles around it. I know it sounds funny to you but I missed something big - right under my nose! Hmmmmmmmmmm.
