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?"
Not really news. You can find references to the caves in an old PCG publication I have. The best one was in Emma Place now under a car park. It had a tidal sump! Attached is a pic of one of the Cattedown Caves with late Bob Cawthorne.
