In an effort to clean the pool and the pool cover ~ I needed to let the pool cover dry....so, i spread it out on the grass and left it for a mere 24 hours. When I picked up said cover to fold it, this is what I found...

who knew a plastic cover on the grass in the blazing hot sun for 24 hours would do such a thing?

Actually, I think a UFO may have landed in our back yard!

At least it wasn't the front yard!
Lesson learned. You're welcome!
