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?"
A couple of my non-caving friends have asked the same question. Visitors that we (DCC) have have taken down the copper mines at Alderley Edge have mentioned it would be a great place to hide out in the event of zombie apocalypse
