Well, I finally got a good look at the fellow that has been stalking me all week in the water in front of my camp.  It is he, not an otter, but a dreaded Beaver!  RODENT VARMINT!  He is no longer cute but a menace, funny how a little difference in the tail can make!  WHAM BAM instead of cute and pointed.  I think he is living under the dock as he seems to always be watching me.
