I have been reading through all of the various posts on the subject of second, third and fourth entrances to Ogof Draenen, and have finally plucked up the courage to add my twopennyworth.
Having discussed this at some length with a number of fellow cavers, both members of my Club (RFDCC) and work colleagues; here are my (our) thoughts;
1) Why do we go caving? Primarily because it is fun and exciting. Whether the people I cave with are unusual I cannot say, but the vast majority of them admit that conservation comes a poor third to fun and excitement.
2) What type of trip do most cavers love? A through-trip.
3) What do we hate? Access restrictions. We accept them where they are imposed upon us by landowners, but find it hard to accept them when they are imposed by fellow cavers.
I have some experience of attempting to conserve a precious cave, being Chairman of the RFDCC who, with GSS and Hades try to look after Otter Hole. We administer the access procedures, as instructed to do so by the landowner. Whilst we are content to do this, in order to maintain access for all, we are also actively digging in the hope of securing a second entrance. This would give us a superb through trip, with hopefully fewer (or no) access restrictions.
I do not personally know any of the members of the PDCMG (at least not that I am aware of), so I cannot say for sure that their actions are not based solely on a desire to conserve the cave. However, it looks to me as if their actions are, to some degree at least, guided by a desire to retain control over the cave (and who enter it). If this is at all the case, then they are acting for their own interests, and not those of either the cave or fellow cavers. I cannot say whether the "one entrance" stipulation was instigated by the landowner alone, or whether the landowner acted upon the advice given to him by the PDCMG.
Ogof Draenen appears to be a cave that has multiple entrances, albeit blocked with debris. I have not heard any suggestions regarding mining artificial entrances, merely digging out natural ones. This is what cavers do, so please get on with it.
I am going to read through the early accounts of Draenen exploration, and may be back with more.
