I truly don't understand the appeal. What is enjoyable about this experience? I like risky and athletic stuff and have done a bit of climbing (nothing technical) and the appeal there seems quite obvious - in addition to the adrenaline rush, you've got clean air, beautiful vistas and scenery, etc. A pitch-black, dank hole in the ground - ugh. The thought of getting lost, especially getting lost and losing illumination, seems like the ultimate nightmare. On the plus side, those big caverns with various mineral formations do look quite spectacular. But you tell me, what's fun about this?
