The Yukon is the only territory that doesn't use them, it makes me sad. I want a polar bear on the back of my car.
It takes a special sort of person to be able to live in Nunavut-really, live anywhere up here besides Whitehorse or Yellowknife (And even still, when I tell people where I live when I'm back in the world, I get weird looks). There are a lot of people who do go out there because it is so remote-that's half the appeal. There's plenty of places where people actually do get around on sled dogs, or on a quad or skidoo. Hell, Old Crow doesn't have more then a handful of cars for the entire village.
Personally, I could never live there. It takes a special kind of weird, that's for sure.
