The Post Office, Dolphins and Rays
On one of the Islands here the is a "Post Office" where people leave letters for other to pick up and to deliver. We left a couple and took a couple to deliver in Holland. It actually seem to work better then our TNT post system with all the strikes...
On our way the captain saw dolphins and we were off with the Zodiacs to watch them. They too were happy to see us and stayed a long time in our company. After that we visited a shallow mangrove bay where the rays get serviced against parasites by small fish.
