Cheers for all the info folks.
I've now left the south on the way back to the highlands and am staying with the lass' family in Staffordshire so lack of rock isn't an issue.
I'm originally from Somerset and so not surprised by the lack of bouldering, but definately surprised by the lack of a sufficiently keen/mad bouldering scene to try to do something worthwhile. There are defintely one or 2 places that would be pretty good if there were enough folk on them - Croscombe, Brean bouldering, the Toll Road and some of the wee caves by the road higher up Cheddar Gorge for a start.
Anyhoo, not my problem now!
Cheers,
Gaz
