The guy is from Minnesota. I would have expected more foresight.
Coming from Winnipeg, Manitoba.....which on average is significantly colder than a lot of Minnesota, it should be second nature to have extra warm gear/candles/sleep bag etc in the car or truck. People die from the weather with regularity. Farmers die of exposure because they get lost going from the house to the milking barn early in the morning. People are found frozen in their cars 4 days after the end of a wind storm. Doesn't matter how much snow is falling, it's the sideways snow, along with the low temps, that is the problem. You are raised on a diet of news that drives home the point....be unprepared for the cold and you risk your life. And not in the theoretical sense.
Dal's comment is right on the money and really, the only part of this thread that has value. For those who don't know, or haven't considered what may happen, it's time to prepare a life saving kit for your vehicle.
