The dome is actually about 2km off the closest main road, being the port wakefield road. It is located at a place called Buckland Park which serves as a research facility which also does meteor counting via radio waves aswell. I think the Dome looks quite modern and only there to serve as a cover for the radar dish, if you think that is ugly then take a look at some of the observatory domes around the place, at least they serve they're intended purpose.
Ving: I have found about 38 Caches now. I don't own any though.
For those that go with the Golfball theory, it doesn't have dimples
LOL
