I second wunderfool's comment. Having driven from Richmond, Virginia, to Anchorage, Alaska, a couple of times, I can attest first-hand that most of North America is unoccupied, empty wildlands. And, don't tell me that I was confused by giant farms in Saskatchewan or something like that. I'm not counting them. Most of the land is simply empty and devoid of humans. (This fact got a little worrisome when it was night, I was low on gasoline, it was snowing, and I was still a good distance from the next "town" on the map.)
