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?"
Out of interest, how detailed is it on Ceunant Ddu? (rather than Foel Grochan and Hen Gloddfa)
I read that Ceunant Ddu was connected to Abercorris and at one point, parts were worked from Abercorris, which sounds unlikely... but read in the gazetteer. If true that'd be an interesting through trip, assuming it's not flooded then collapsed.
Are there many clues in the book to confirm/deny that, if so I'd order a copy
