During Christmas 2013, we went on a cruise in the Caribbean. The sailing started from Miami and for 7 days, we visited several Caribbean islands. We also spent a few days at sea. The only thing in sight, 360 degrees, is the horizon. Here are some pictures of the horizon taken at different times of day and at various location on board and on shore.

Beautiful and lonely … the horizon was what the explorers saw for months until (if they were lucky) they found an island or a continent.
