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?"
It's a while since I went, but nothing to lose by giving the owners a ring at Stump Cross as Mary's Boy suggests. It used to be that all in the party (must be more than one!) sign in the book at the show cave, then they're happy.
