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?"
Do you mean Batcombe near Evercreech, or Batts Combe Quarry near Cheddar. If the former, dunno, but I'd probably ask Mrodoc on this forum; if the latter then check out the Mendip Cave registry & Archive.
Its batcombe near evercreech i have been searching around there and all i have found is an interesting sink and on the other side of the hill is the spot where i was digging but got told to stop1
