Fair comments, I'm sure 99% of us are in favour of Twll du staying permanently open and that this matter can be concluded.
It's an (accidentally) illegally dug entrance in the middle of a scheduled monument...
From the outside it looks like the Draenen situation has been going on for so long that there is no room at all for reasonable middle ground, and people go as far as possible in one direction or the other regardless of whether it is sensible or not.
I don't believe in a single entrance policy. I do believe in respecting the hard work that caving volunteers put into managing caves, whether you agree with their actions or not.
I do believe in respecting landowners, but I also believe there should be a right to go caving where that does not impinge on others.
I do believe in protecting preserving our archaeological history - and I believe it is right that Cadw is empowered and active in doing that. The Offa's Dyke case was a farce.
I do believe that cavers, as the law currently stands, often trespass on other's (underground) land - but without harm to the landowner.
I don't believe that cavers should engage in outright criminality - whether it is causing digging damage without permission or knowingly damaging a scheduled monument.
I do think it is very unfortunate that Twll Du came up where it did, and if it had come up somewhere else it would be a great entrance - but it is where it is.
I believe caving needs to come out of the dark (so to speak), and present itself as a law-abiding sport, like other outdoor sports. This is how we will get greater acceptance, and with it greater rights to caving. The way to do this is not tacit acceptance of criminal behaviour in flagrant disregard of statutory bodies put there to protect our heritage.
I believe it's not all about Twll Du, it's not about Draenen, it's not all about the PDCMG and the CCC, it's not even all about caving - sometimes people need to see the bigger picture.
The only way there could ever be legitimate access to Twll Du is if Cadw agree - unlikely, but I expect my access bodies to be trying, not disengaging. Perhaps they are already satisfied it is not an option - in which case they should be working to rebuild relationships with statutory bodies. Hopefully I shouldn't need to explain why.
What is the possible gain of this course of action? What can be gained by withdrawing from debate with the only body who could offer legitimate access?
I'm sure there can be other entrances.
I may or may not _want_ Twll Du closed, but I accept reality, and I see no benefit in damaging relationships and fuelling the fire where there is little to no hope of success.
