You're right there in terms of distribution. The global nature of them is a big part of what fascinates me about them.

When I said a northern thing, I meant that it seems to be mainly northerners who are interested in these isles. I was a bit zonked at the way that those cups on Fyfield Down were so ignored, given how much archaeological investigation has been done nearby, but I guess they just get eclipsed by the more glamourous stuff (which admittedly does yield more data).
