Every year, as the snow hits, I "play" with the kids in the car in controlled circumstances. The points is to 1) re-awaken my skills and 2) give me a teaching opportunity with my kids. Dealing with an out of control situation in the ice is challenging enough when you are prepared. If you are constantly freaked out about the snow/ice, you are in big trouble when something unexpected happens.

It's also a lot of fun to deal with a car that is borderline out of control in a more controlled environment.
