Interesting; do you have any more information about this corruption of the definitive map?
'The Corruption of the Definitive Map', is a phrase I originally coined to raise the subject on the long since defunct Rambler's Forum. It described the effect that the self interest that those local government appointees from landowning backgrounds contributed to the formation of the Definitive Map and went against the will of Parliament.
On that forum I wanted to see if there were people out there, who could recognise the traces of this on the ordnance survey map. I ran a topic on that forum for over a year until they pulled the plug on their forum and went all FB and twitter. The topic got a fair number of hits but it was only after it's demise did I learn that there were a number followers, who were active on footpath business.
I have collected quite a number of examples, walked the hallowed ground of "private estates" and proved to my own satisfaction that there are probably over 500 miles of lost way in Shropshire, which could be earning the county many £millions per annum in direct and indirect revenue.
Sadly since Piddle Bucket or whatever calls itself now tried to extract £300 from me to host photographs, most of the illustrations on topics I posted here are probably not easy to understand.
Included in those topics is my discovery that the president of the CLA, who would have been editor in chief and probable author of the 2012 CLA policy on access, which they claim as common sense, farms a family estate in Herefordshire, where there is and area of 11 square miles without any rights of way (despite an interest network recorded pre 1949 by ordnance survey). He also failed to recommend any policy that landowners may adopt if they have important features on their land of historical or natural importance. The Garnon's estate has an important section of Offa's Dyke in it, which probably explains its historical function, more that the fictitious route this way takes 10 miles away off course.
Personally I think the NFU are foolish to allow the CLA to get away with the infantile nonsense they spout, sadly this professional body does not have the wise heads that coached me as a young farmer, when I took the chair of a group branches many years ago. Since I got thrown off a Local Access Forum as soon as a hereditary landowner took the chair, there is little I can do, except carry on exploring, though my days out are less active than they were.
I keep on trying to add to my portfolio on The Corruption of The Definitive Map.
I think there is enough logical reason to argue that a private estate with formal drives in and out is in fact an area of lost ways. The Landowners themselves have provided the reasons in their own arguments about the impractical nature of our rights of ways network to provide the basis of this reasoning.
