So what has happened since, is the ley-line idea still fashionable or simply seen as a hit and miss or chance thing? .
Yep. It's unproven mumbo jumbo. There are so many things in the landscape that if you look for patterns for long enough you'll always find things that line up. Just cos they do doesn't mean anything.
Wot she said.
No. I don't agree at all, but then it's all down to the experience/experiencer. That way possibilities lie.
