My $.02 on the matter is this. When the snow starts flying I go and find a desserted stretch of road. I prefer out in the boonies. I practice losing control and forcing a skid. Then I try to recover from it. I do this till I have yet again learned to do it instinctively. Doesn't usually take to long and every year that I have driven in foul winter weather I have been thankful I have done this. It certianly hones my reflexes.

Drive safe.
