It seems we are all of the same mind when we talk about finding some unspoilt solitude to appreciate nature and a sense of the timelessness. Speaking as someone who lived in London for many years and found entering the Underground something that took a certain amount of gritted teeth resolve - getting out onto high unpeopled places is one of my great joys in life. It is disheartening though when places like the ancient Ridgeway become unwalkable because it has been churned up by 4x4s and motor bikes.
Interesting debate... perhaps my favourite passtime is trying to determine what it is about a location which may have singled it out as 'the spot' for a particular monument. For me it entails trying to let go of all we've learnt about the world in the millennia since and try to walk in their shoes. There do seem to be emerging patterns.... the gorsedds, sightlines etc. One day I guess I'll need to lock myself away and sift through it all. In the interim I need more data! At least that's my excuse for hanging out on hilltops and the like.
