The shadow is the ghost?
Yeah, there's a weird shadow that moves when the tree falls. Shrug. Is what it is. If you watch the enhanced version, I used premiere to highlight the spot.
I don't know what it was. I had just noticed that the tree was down so I went back to see when it fell and noticed that weird shape moving off. Go figure. It could be a dust cloud...except we had been having soaking rains for weeks. It's just weird.
