Jamie- what did the formation room look like? how big is it? did you take any pictures? i'm too chicken to try and go that far back. it sounds fascinating.
i'd try it, but i get claustrophpbic. it sounds like Karen's crawl is very long and very narrow. the same with the wire wiggle. once you get that far back, if you start to lose it, start getting that trapped feeling, get tired, etc. there's nothing you can do. there's only one way out.
tell me about the formation room please. thanks.
