I agree and am currently engaged in a prolonged in depth study of waymarks, trade routes and boundaries. Often particularly difficult for two reasons:

1 The Romans "improved" and developed earlier trackways and too much emphasis is placed upon routes as being virgin Roman inventions. Look beyond and before.

2 New age mumbo-jumbo and earth energy fantasy means that few serious writers look at prehistoric tracks and non astronomical alignments seriously.

The key is found by trying to understand the geography - not the cosmology or religion. Landscape is key. Look at the landforms, the valleys, the wet places, the heavily wooded ground, the fording places. These were the factors that determined communication and trade. That leads us on to understand why straight lines were sought and routes marked. Perfectly reasonable then to see barrows and ritual places associated with routes of passage as well as rites of passage.

<Kevin's theories have been fascinating to read about...<

Sadly, I cannot share your fascination with Kevin's theories moss; I find them fanciful at best, irrelevant to the general theme of TMA somewhere in the middle, and tediously egocentric at worst. He is, of course, welcome to pursue his theories in his own time but not in mine. I no longer respond to his posts and from today will no longer be reading them. For what it's worth (and it's already been pointed out by others) there are plenty of other public message boards/websites where Kevin would find kindred spirits and a far warmer welcome than here - perhaps he should now begin to seek them out.

>My theory is that once you "make a place in space" other things start to assemble round it, especially in such a lived-in place as Britain...<

Yes, I totally agree, and I've said elsewhere that I believe Avebury is, where it is, because of the quality of flint in the area and its proximity to the Ridgeway.
