Might as well ask where I would NOT want to go... It would be a shorter answer...

In any case, I would like to go through central Asia. The landscape of Kazakhstan, Uzbekistan, and all other -stans looks really nice. And Ive seen some really cool pictures of Astana (Kazakh capital), and it looks like a nice and clean city. Not really what Borat Sagdyev would have us think.

Oh, and I would go to the Americas - specialy South America, the andes and the "badlands" (or however you call them) in the N. America.
