I was going to post one, I have just been working a lot recently I will wait until I win the next one
I think the new one is Nine Barrows Swallet :-\
I have never been to Totty Pot, but I was sure the surrounding hills looked like the approach to Cheddar Gorge: a route of have been through many times!
Unless things are very different from 20 years back, I recall Nine Barrows entrance being either at the edge of a field, or in a clump of bushes. It was a LONG time ago, though!
I reckon that's an easy one, Chris. I shall refrain from posting what I believe to be the answer as I've not yet uploaded any pics to continue with. 8)
Went there some years ago - it's a squalid little hole thats just begging for a load of ready-mix!
