Show me some that lie on Great Circles (the shortest distance between sites on the curvature of the Earth's surface) and I'll start to look at them.

That was the case with the Tables des Marchands figures .

I like inter-site sight lines.
Basis of archaeoastronomy . Very, very important. As are most celestial/landscape feature alignments in my mind.
Much more difficult to prove intentionality than above .

I just can't begin to consider the energy line stuff at the moment.
I doubt I ever will .
