Potholing Grannies!

Same here; I can understand people climbing mountains but the thought of going underground makes me go all shivery. I may try to watch the programme on catchup but may have to stop watching it as it might give me nightmares....

Me neither. I know someone who goes caving, the caves are fabulous but she has to wriggle through tunnels etc at low tide to get to them. My idea of panic-stricken hell.
I cannot bring myself to go under the Channel Tunnel.

I used to do it in my teens. Living on the edge of the Peak District we had caves and old mine workings in abundance to explore. Our F E college had a small club and we would go out weekends in the summer - too wet and dangerous in the winter. Some of the things you see created by nature in cave systems are jaw droppingly beautiful. Couldn't do it now - some of the passages were a nightmare and I was as thin as a rake in those days. My mother used to have kittens every time I went. My own DD went a couple of times to Settle with an outdoor activities club she belonged to for a while, and then I knew just how my mother felt. I must say, I haven't seen the programme but I have the utmost admiration for these ladies. It takes stamina, and not a little strength, to negotiate some caves.

Me too - talking of nightmares I used to have one about being stuck in a dark place and fighting to wriggle out.
They say that kind of a dream is the birth experience - but I don't want to go back to the womb, thankyou!
