I will never dive into Jacob's Well like this fellow did no matter how many times I see others do it without killing themselves. The water is so clear it never looks deep enough. And the blue hole at the center seems to leave little margin for error.
Jacob's Well is the entrance to a long watery cave. Some people actually scuba dive into it. Not me of course. That's clearly crazy dangerous. But folks dive it anyway. And some don't make it back.
