Dolphins

I had been trying to explain to Jeff that we would see several Dolphins on our journey. He seemed reluctant to believe me until 4 or 5 joined us, frolicking and playing around the bow, doing what dolphins do in a bow wake. Jeff got many pictures, and some great video footage. Truly magical creatures.
