The surprising thing about all the public beaches in Biluxi, Mississippi is none had any rest rooms.  I had to use a Marriot Hotel to use the facilities.  We looked at the water line (of the high tide) and realized there really was not much beach left at high tide.  I walked along the beach and found a large head of a fish (I had no idea what kind of fish it was) and also a big jelly fish at least eight inches long and five inches wide.  Otherwise my walk was uneventful.  I did see a dozen plover play tag with the tide.  They would run around the waves and stick their heads in the sand.  I had no idea what they were eating.  I did get wet completely but the Gulf was not that deep.  It was a pleasant afternoon.
