You are one brave person. I have to agree with BajaRon about the safety issues though. Driving winter roads at night can be dangerious. One patch of black ice in the dark, at high speed, and you could end up in a ditch, crossing the center line, or running into an oncoming car. Things happen fast, even with the nanny on board. I also know you have a deer hazard, especially at night in MN. We encounter black ice all the time here in Alaska. Every time its on the road I see several cars, and trucks (even with 4 wheel drive) laying upside down in the ditch. I commute the Glen Highway into Anchorage, every day and have seen as many as 25 cars upside down in the 15 mile stretch I drive. There was a car in the ditch yesterday on my way home--and it had not snowed for 24 hours. They just hit some black ice--and away they went. There have been several deaths over the years from this--I actually saw one happen three years ago. I dont want to rain on your parade--but IMHO, the thought of someone being killed, does have a sobering effect on me. Please drive safe.
