It's an interesting list, all right, but it's a little deceptive unless you keep in mind that propagation plays a huge role in what makes it to the US or not. I would bet most of those Georgian logs were from European listeners - such targets are quite difficult in the US due to propagation (and time) differences. Using utilities like SunClock or the popular GeoClock shows this sort of thing very clearly. There are, no doubt, many other such software packages that predict sunrise/sunset in various parts of the world
Something for the new folks to keep in mind.
