In my experience of caving (2 1/2 years with a uni club - i.e. spontaneous, lazy and only visiting 'popular' caves) access is not really a problem (Easegill, Castleton 'area', Gaping Gill, Alum, OFD, Aggie, Swildons, Cuthberts, etc.). We have had problems, Leck Fell has a waiting list longer than our member list, GB and Rhino keys are now ?20* (from WCC, free at BEC (with hut key), unsure of SMCC) which for a minibus full of cavers comes to an eye watering ?60 and Box has only one allen key at the pub. DP can bang on about the glorious access at Box but we couldn't get in the other weekend and can't find a shop that sells 17mm allen keys (locally/on internet at least and not in a set with 30 other allen keys).
As for local language, these arguments really annoy me, I don't mind the theory but forcing a language because it's in Wales (for example) is just trying to be politically correct/to give the locals something else to grumble about, it'll only get abbreviated to OFD, Daren, DYO, PYO anyway. Besides isn't English also an official language, more people speak it anyway? The English/British/Irish/Scottish/Welsh are a mongrel race. Saxon, Viking, Norman, Celtic, Roman, Phoenician and everything else in between. These are just the 'current' fashionable languages, what about Cornish? Should all caves in Yorkshire be spelt in 'northern'? Besides I thought in S. Wales English was more popular hence it comes before Welsh on the road signs, north Wales is a different kettle of fish...
*at WCC you also have to go through a lecture (argument) on cave leadership and generally deal with hostility (from more than one person), I walked out last time.
