I am all for a ley/dousing separate section. Then maybe all the other forum postings won't just end up about dowsing, then degenrating into slanging matches.
I "know" that the ancient sites were pretty much a prehistoric tescos. Situated to be visually prominent from major traffic routes, constructed on a much bigger scale than the rest of the buildings, built (generally, please don't shout!) in a fairly crude way, but with plenty of car parking space available...... I think it's why some areas have so many remains. Bet the people of thornborough were saying "but we already have 2 tescos right next to each other. do we REALLY need another?".
