Deer in Pool

I was sitting on the couch talking to my wife and daughter when I saw something move out of the corner of my eye, in the yard.  I thought it was a dog at first, but the back yard is fenced in.  Then I realized it was a baby deer!  We have lots of deer in this neighborhood and have seen a few babies recently.  Probably just squeezed through the bars in the iron fence out back.  Before I could say anything he scampered toward the pool.  I figured he wanted a drink, but he dove right in.  Maybe he does this all the time.
