Yes - lots of people do. The book about standing stones on Anglesey that I bought from here was based on a similar viewpoint. It is in no dispute that standing stones have been hypothesised as waymarkers, as one of their functions. This man's theory just goes further. Then imagine our road network stopped being used - petrol ran out say - and what kind of remainders would there be left in four thousand years ? (Personally I just think there was a network of paths communicated by oral knowledge, but there you go).
