When he and I went out to investigate we saw that a LOT of water had come out of the pool and that all the ground on one side of the pool was really wet.
The first thing a person thinks since it is one of those great big Walmart pools is that it sprung a leak.
We looked and looked and never found a place where water was still coming out of the pool. Finally on one area of the pool's side, as I held up my flashlight (this was after dark) I noticed that water had been SPLASHED on the side of the pool.
I called Gene over to see and we both made the conclusion that it must have been a deer and that the deer had managed to push down on one side of the pool hard enough to let out water before it ran off.
The logical thing to assume is that it pushed down with its front feet as it stood outside of the pool but if you saw how MUCH water we lost and the splash marks, I think you would wonder like me, if instead the deer had actually been IN the pool!
