Snow, that is.
If I have one more Yankee look at me conspiratorially (because at work I usually do a decent job of hiding my accent) and say that, I think I'm going to go on a rampage, gunning my engine as I fly down an icy embankment, taking out as many parked cars with New Jersey plates as possible.
What does that even mean, anyway, when someone says, "Oh, I know how to drive in snow." Seriously? The only technique I can think of for snow-driving is to use common sense, drive slowly if you are on top of a patch of ice, don't follow other cars too closely, don't slam on brakes, and if you skid, turn into the direction your car is floating.
And if you are proudly lauding your bad-weather driving skills in a two-ton four wheel drive monster of an SUV, then no, you really don't know how to drive in the snow. Because your car does it for you.
As for us Southerners, we will more than likely do the common sense thing after a snowstorm: stay home and wait for the plows to fix everything.
