Actually I was taken into a cave once. I dove the cenotes in Playa Del Carmen, Mexico, back in 1997. I remember being apprehensive at first. Our guide told us that there would be an area where we would turn and penetrate into a cave. There was always a guide line throughout the entire dive and also leading from the mouth of the cave and about 50 feet into the cave. The guide had a powerful light and we all each had our own lights as well. Before we submerged, the dive the guide told us that he would take us into the cave if we all told him we wanted to go in, but to make sure we always held on to the guide rope. I remember looking back at the cave entrance and not being able to see anything but blackness until I pointed my light back and saw the guide line leading in that direction. I remember feeling a little nervous and breathing a bit more rapidly. For a brief moment I thought about how awful it would be to be lost in such a place, just waiting for my air to run out, but I soon relaxed and began enjoying the experience of being somewhere where not many women or men go, and also the beauty of the rocks and formations that our guide was directing us to. When we turned around and returned to the cenote part, I was exhilerated after the experience of actually having been in a cave. You know, even though you could always see some kind of light throughout the cenote dive, you really would not be able to surface for air if you had a problem. You would have to swim toward an exit . Yes there were some areas where you might be able to surface to breathe, like when we surfaced and saw a bunch of bats in an airfilled chamber, but most of it was like being inside a really long cavern. I really loved it! The guy I was with at the time was sort of uneasy with the dive, but went through it anyway so I wouldn't think he was a sissy. I told him he didn't have to but he insisted. So, I come away with the gut feeling that I would like to continue with my dive education. It's just a matter of having the time to devote to the training part.
