Realistically, UK. I dig British culture a ton . At the same time, the art cigarillo in me would love to be somewhere on the mediterranean, possibly Italy or southern France, purely for aesthetics. Actually, France would be an option, too.
It's a tough question. I can't really answer it without asking "which country's culture do I wish I grew up in?" and they really aren't the same questions at all. But I can't separate them. I have something of a resentment for having grown up in the US.
