The last time I went spelunking was 50 years ago in Becky Thatchers cave in Sam Clemen's Hannibal MO. We got lost and our flashlight batteries gave out. When we finally saw a little daylight we found that recent rains had half filled the narrow tunnel to the outside. Crawling caustrophobically with my mouth just above the water scared the shit out of me. No more spelunking, thanks. Good luck to you.I am a novice spelunker, an avid reader of back issues of Tropical Fish Hobbyist (although I don't have an aquarium), I collect and repaint Red Rose Tea figurines, hopscotch, and I have recently taken up Square Dancing although I haven't had the courage to do it in public yet.
