I'm getting my winter kit ready for my car right now. In really cold, icy and snowy weather, you don't have to be very far from home to have a bad problem, especially if you have family members who have health or disability issues.... Hint. I could walk out, but my wife would not be able to. Last Winter, we had such serious ice that a "rescue" vehicle could not get into certain areas.

So the car gets extra blankets, shelter, traveling major FAK and the perpetual BOB with food, water, FAK. and FSK. And also use a little common sense about necessary traveling during bad weather.
