Ha, never seen a dolphin there ever but some people do post they have.  I never look towards the water long enough, I guess.

 

Glad I got to see you twice as well.  You looked strong both times and I saw the 3:15 pacer chasing you when I saw you last.

He was a steady 4-5 seconds ahead of me during the final mile and people were cheering me on to keep up with him, assuming he was my pacer.  No other marathoners were around us.  Must have looked like were flying compared to the HM'ers that were still out there.
