I think the issue is that teh ACO have not made the mpas public. Someone, at another forum, has obtained a map from somewhere that needs to remain anonymous. To view it on that other forum, you have to be a member. Therefore the map is not in the public domain.
That said, Paddy and I have questions as to the accuracy of the map anyway as if you look at the shape of it and the obvious gaps for tracks, it looks like it is upside down and that what the map says is trackside is in fact next to the road!
I'm just waiting until Monday when people start to arrive to find out what the actual situation is!
