A Brief Moment With An Otter

I enjoy encountering the creatures of the Parkway while riding my bike.  They are very used to bicyclists speeding by at 15 to 20 mph.  Me?  I go a lot slower than that as I do not want to miss them.  I saw this big Otter on some raised mud in a slough and had to stop.  He was was preening.  I took a moment to admire him without him noticing me.  Then, he saw me and started looking around.  Eventually he quietly slipped into the water and disappeared.
