Finally I saw an alligator swim up the Phillippi Creek early afternoon. I even watched it turn around and start swimming back down the creek. I saw a duck hop up on his tail. I thought this is what is happening, but after the duck sat on his back I had second thoughts.
Tonight my alligator is an old log which came upstream with the high tide. Where the two waters met the down stream water was stronger that the high tide so the log did a turn around and got stuck at the water's edge.
