Almost moved to Australia.  When I say almost, I mean really, really close.  Job, money, living arrangements, etc.  I may still move there within a year depending on the new lab opening in Australia or New Zealand.   
There's no one place I can think I'd want to live.  How could I make such a decision when I haven't even seen half the world?  Plus, I'm just nomadic by nature.  Everyone else move to different countries and I'll visit all of you.
