You know, as a European you get the feeling of being at the end of the world really quickly when you're in the States.
Here you could never go more than 10 minutes on any road without passing some kind of city or town. But in the States you just have so much landscape per capita... Just driving from LA to Vegas makes you feel to be in the middle of nowhere. (which really isn't that remote for American standards)... I can only imagine what it feels like in Alaska or parts of Canada!
