hminx, thanks!

Gary, the person was partaking in some New Year religious ceremony that some Cubans do. I don't really know exactly what it is, but they take out things to sea. collect water, drop stuff there. All kind of different ways, according to each person I saw. what looks like a fire on the right was actually another person, that was moving a bit faster, hence being almost invisible in this semi long exposure. thanks for the comment

Paula, that's a nice take on this that I hadn't thought of before. civilization vs. primitiveness, I like that. Thanks!
