I had a hard time sleeping last night. I finally got up about 4 AM and went out in the recliner in the living room. I fell back asleep and about 7 AM I woke up. I realized that I was hearing a noise. It was pretty rhythmic. I could not figure out where it was coming from. Then I realized it was coming from out in the store area. I got up and went out there. This is what I saw at the window.
