Only in Canada do you fly through US airspace to get from one point of the country to another.

Flerfers on life support!
Only in Alaska (and maybe Minnesota) do you have to drive through Canada (without your handguns or potatoes) to get from one point in the state to another.
There is a great story called Journey written by James Michener about Brits who wanted to traverse to the Yukon gold fields without going through America territory. As I recall, the Brit servants all died, but the expeditioners got through fine.
I love Michener, I'll have to check that one out.
