Karen,
It's -3 C here now, though I think some places are colder than that. It's weird what temperatures you can get used to. I spent a year in northern Greenland, so 0 C AND sunny AND no wind was BBQ weather!
I'm not too particular about location, although somewhere near water with (green) trees and some sort of seasons would be nice. I'm okay with hot summers and cool winters, just not the same all year around. My wife and I have friends in Perth and Melbourne, so that would obviously be a plus for those two locations. Schools are important too (uni/ primary/secondary).
So maybe I am particular about location, after all!
Thanks
Alistair
