If you look at the picture above you will see a colored umbrella on the beach. Above that umbrella are three people in the water. Above them is a dark colored object in the water. That dark colored object is a school of manta rays meandering off the shore. It was cool to watch as they would approach a swimmer and split up to go around, then regroup again. They didn't move too fast and we saw them going the other way later in the day.
This was Don and Debi's highlight of their vacation.
