I don't have a GPS, and I don't particularly want one. The issue is that some people will dutifully follow the GPS, while not having a clue as to where they actually are, this can be a problem when a road is only partly winter maintained. I have seen roads where the snowplow actually turns around at one point and goes back, leaving a big snowbank in the middle of the road. If you do not realise that this happens, you can run right into that snowbank. They usually do this, because there are no people along that part of the road, so they don't want to spend the time and fuel to plow it.
