Thanks for the reply. In terms of West Kennet Avenue, to an extent people walk down a certain path because they are "told to" by the grass being cut short or worn down...
As a final comment, I was slightly disappointed that the path over the hill has been removed, as it never seemed that busy or worn, and gives a wonderful view of Silbury Hill. Is there still open access here?Also, I notice that you've named a path "The Ridgeway" which isn't on the current National Trail. Is this part of a plan to divert the end of that walk?
