Welcome to the forum Mike, I totally understand what you mean about floating through passages as opposed to crawling through them (just had the right hip replaced, 3 more major joints to go.) I still enjoy dry caving, but I do often stop and think how wonderful it would be to be able to scooter through some of the passages. The annual CDS workshop is coming up Memorial Day weekend in Live Oak, it would be a great opportunity for you and the Mrs to meet and connect with a number of cave divers from all over as well as hear some exciting stories about our history. Hope you can make it down.
