We had a two week cruise over in the Caribbean calling at ten islands. As you can see from this photo taken in Antigua, the Ventura is a huge ship and can carry 3200 passengers.  I had to give four talks while onboard.

On Grenada, I went tubing on a river with rapids swirling down through the jungle. Of the 12 of us doing it, I was the only one who got a puncture and got left, deflated and marooned on a rock until rescued by the leaders of the flotilla.
