Not sure how they can deliver firewood when the roads are impassible. And in very heavy snowfall -- esp dry powder that you get when the air is, and stays, very cold -- you'll continue to get significant amounts of snow on the roads long after it stops snowing as the wind blows it onto the road.

Additionally, a well-maintained suv with 4wd and snow tires isn't a cheap thing to own and maintain.

And if you get your car stuck somewhere with wind chills dipping to -50F, dying of hypothermia is a possible and/or likely outcome.

You can really tell who has never lived through a serious winter.
