I have never, I mean never, wanted to go cave diving and I still don't and I didn't even see that scary cave movie that came out recently, but my boyfriend brought home this little pamphlet that shows where you can do it and how they do it blah blah blah. Only kidding, but I was slightly interested!
There is a section of the pamphlet that talks about where you can do zip lines which seems like it would be more in my range. It says that you are 1500 feet above the ground and will travel up to 40 mph which seems pretty exciting.
I can't say that I wouldn't still be horrified and afraid that I might bust out of the safety clamps and fall to my excrutiating death, but I just might consider it. I can't say for sure though so I guess that even my consideration is "just talk." If I manage to get myself up there the people below had just better watch out for scattered rainshowers.
