It wasn’t too bad when the wind stopped–only about -3 to -6 Celsius. When we arrived in Minneapolis, it was actually slightly above freezing. I managed to screw up my back somehow en route. I’m not sure how. I think it was a combination of nasty airplane seats, improvised pillows, five hours of journey, and cold gray weather. We managed to rent a Prius. The logic was that although it isn’t 4 wheel drive, on icy roads it’s better to know exactly how the car will handle and how effective the brakes are.
