Yes, I plan to be at the grotto meeting. I suspect one of the cave divers you are referring to is Forrest, and I have known him for several years through the CDS. When I lived in MA, Forrest gave me my first exposure to 'dry' caving at the NSS convention in VT. I put 'dry' in quotes because I got wetter in that cave than I have ever gotten while cave diving. So, when I moved to GA and he offered to take me dry caving locally in a cave "like the one in VT," I prepared for another complete immersion. I was pleasantly surprised when the water didn't even go over the tops of my boots.
