I'm a Gainesville resident until I finish school, and this is cave country. My instructors are cave maniacs that often fraternize with GUE instructors, and they are always on us about not ever ever even thinking about sticking our head in a cave without proper training. I agree that all courses, especially up here, should include some sort of literature or presentation on cave or even cavern dangers. Just today I had a dive at Paradise springs, nice spring, but to call it open water is, I think, a little sketchy. Paradise springs for those of you not familiar is a hole basically, about 15ft across, and 100ft down on a rather steep slope with plenty of over head. I'd say its about 200ft from the 100ft cave entrabce to the opening. It was a nice dive but still a little intimidating for an open water diver. There is a line, and you are allowed to take lights in, but it silts up rather quickly. Well just my $.02.
