Going to the States is not really on my mind, but because you ask.

If I could go for at least some months (it takes a while to get a feeling for a country you don't know) I would like to visit the parts that are really different from most of Europe.

I think I would visit about 3 states/NPs, say Arizona, Yosemite and Olympia.

But in now way I am bored by visit the British Isles, Scandinavia etc.
