Orion and Orkney
I have a real love of Orkney and actually got to visit there once (and I've always thought Methos was raised at Skara Brae). One of the best websites for the islands is Orkneyjar. I hadn't been to the website in a while, so was browsing what's new, and came across this article: On earth as it is in heaven - was Orion linked to Orkney's Neolithic heartland?
Fascinating stuff -- and Orion is my favourite constellation!
