I had my inflatable kayak just over the second sand bar and saw a large dark spot on the bottom just off to my right. As a rowed over it, it surfaced on my left, took a good look at me, went under me and surfaced for another look to my right. It then swam over for a look at a woman on a paddle board who had spotted it and was following. He then swam off to the east I was no more than five feet face to face and it was either a manatee or large seal of some type, but I'm not aware of seals around here. However, I was unaware manatees came this far north. In any event, it was a thrill and made it worth lugging the kayak from Texas.
