It's not. Trust me. I think that I would stay in the exact place where I live now. It has its problems, but I'm happy here and this is where I belong.
Kyoto, Japan. I've always loved that place. But since I doubt I'll ever get there, Colorado isn't too bad.
I've been seriously considering Arizona. It seems nice(mostly). No ocean, though. That might kill me.
Probably somewhere near Kalispell, Montana. That whole area (especially around Flathead Lake) looks absolutely beautiful.
Zurich, Switzerland. Or somewhere in the Netherlands or New Zealand. Italy, maybe. At least I already have the citizenship, but I'd definitely choose northern over southern.
