Thanks for the advice. I usually go to Les Schwab and tell them I want studded tires and I want to see nothing but sparks and cement dust. Unfortunately it is hell on the roads. I'm going to give these a try.
BTW. I spent the winter in Calgary back in '98. That's where I learned that the old saying "it's too cold to snow" is BS. I realized this when I went to cross a street, 40 below and I could barely see the streetlight through the snow that was moving horizontally. I was impressed with the way Calgary handles it. I guess you either get tough (and smart) or die.
