Recently there was long thread about the BCA. I can now post possible answers to some of the questions, such as "Why is the BCA still raising membership prices when there is a significant amount still left in its coffers?"
I seem to recall somebody putting a post up about Dorset specifically Portland. Have now scanned my slides and put them on the internet at http://www.darkanddeep.co.uk/caving_dorset.asp for those who might be interested.
