This is kinda a neat ball in the photo, I took the pic but didn't see it as I took it. This ball is not a sun spot, rainy gray day...It makes me think of (but it is not) ball lightning I took pics of a few years ago, that I did see, photo'ed 2 pics of it, and it was real...
It floated towards the bench in the background.. pic takens seconds apart, click-click
Cat under bench hiding.
