I take this topic seriously.

A few years back, I was driving for work in a snowstorm in Northern Minnesota. I had a 4x4 Ram pickup. It was about 8:00PM, 1 degree, breezy, and snowing steadily when I hit a snowy curve in the road. The remote area road was lightly traveled, especially at night, and had been plowed extra-wide by the county truck to accommodate a heavy snowfall. The plowed shoulder was flat and looked like roadbed, but it was actually soft snow over a boggy area next to the narrow road. My truck got stuck, high-centered, and tipped at a 30 degree angle toward the ditch.

I was familiar with the area and knew no one would be coming by anytime soon. I didn't feel that staying in the truck was my best option, so I walked to a gas station I knew was at an intersection 3-4 miles down the road (actually turned out to be 7 miles). I had my deer-hunting clothes and boots with me, so I put them on over my lighter work clothes and made the long cold walk.

I now carry a more extensive kit including a heat source, wool blanket, a backpack, hot hands, a metal cup, etc.

A lesson learned the hard way.
