It's pretty simple really - take your time, light on the throttle, and thinking ahead to carry momentum are key. For example, when coming up to a hill with other cars in front I purposefully slow down ahead of time to increase the difference between me and the car in front so I can then carry my speed up the hill and not worry about the car in front. I find turning off traction control on the 94 is key in deep snow. Getting that tad bit of wheelspin makes all the difference in getting going. Only two times I got stuck, the TC was on. Weight in the trunk (I have two cast iron cylinder heads in there that I never took out after picking up from the shop in early winter), and keeping the tank at least half full makes a world of difference in traction - remember, we can carry (relatively speaking) a crap load of gas, and that equals weight.
If sliding straight with wheels turned, let your foot OFF the brake to regain traction and turn.. Downhill, shifting down to 1st or 2nd to use the engine brake helps a lot.
At least once a year, at the first snowfall, take your car to a lot and get used to recovering the back end trying to overtake the front at different speeds. You *will* break loose over the winter, and the more second nature it is to recover, the better off you are. As good as I think I am, I always realize how rusty I am each year, and a half hour brings me back up to speed - I don't want to be "rusty" and re-getting used to it in a panic situation.. Personally, since snowfalls can be few and far between here in Toronto and the rest of the time the roads are relatively dry, I go for a 30 min drive every time a couple of fresh inches drop. First of all, it hones the recovery skills, and second pulling low speed powerslides is a hell of a lot of fun, especially in a car as big as the Fleetwood
And lastly - for god's sake, get a decent set of winter tires if you live in the snowbelt.. All seasons were *never* meant for our kind of weather, and once you try out a good set of winters, you'll wonder why you ever accepted all seasons for winter use in the first place. Personally I hope Ontario takes Quebec's lead and makes them mandatory - we'd all be safer.
