A few comments in a local rag, and debates on a forum are hardly a 'public campaign' anyway.
It's about time some people got a sense of perspective: caving is a minority sport/pastime.
Very important to those that do it, it's virtually invisible to the general public (unless there's a rescue), mainly due to it's nature.
To most people the question of open access to caves is an esoteric irrelevance. And herein lies the problem. BCA can throw money at CRoW all it likes, Tim can conduct a campaign of brilliance, but the whole thing will be ignored by the bulk of parliament and the public. That isn't the fault of those questioning the Constitution, or conservation, it's just the nature of the beast.
I can't help thinking that if a similar effort (and there's been a lot of effort, I'm in awe of the work Tim's put in on this) was put into revising the permit system for the Dales, then there'd be a lot more to show for it.
