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?"
My Pentax waterproof camera in a black soft case was accidently left in the Long Churn Cave on Saturday 19th June. Probably between St Pauls and Diccan entrance but cannot be sure as someone else was using it.
Don't give up hope. It could have been dropped in the field on the way down, in which case someone may still find it. Or it could be anywhere else that you went in Long Churn - we only looked from Diccan to St Paul's, 'cos we were on our way somewhere else.
If worse comes to the worst and you don't get it back, it might not be that someone's nicked it - there was heavy rain a couple of nights before we went, and I imagine that would have raised the water levels.
I will not give up hope - as you say it might still turn up. I lent it to some friends and I was not with them in the cave but it seems that area was when it was last seen. Anyway there are far worse things that can happen. Thanks for looking.
