Kudo's to Jim for starting this excellent thread! It is important!
Jim gave some excellent suggestions, the only thing I might want to add, is if you absolutely have to go out in your car, besides having blankets , make sure that you have good warm boots and winter gear in your car with you, and also a good first aid kit, and water and some food, snack type food is excellent and a good cell phone, extra batteries and flashlight, and also make sure that you alway keep your gas tank at least half full in the winter.
In the winter I always keep a "winter survival kit in my car, with a warning triangle, and good flash light, and a coffee can and candle., and matches. and even some extra pieces of wood. I have Just about everything in it. If you get stranded in your car, stay in your car, and do not go out in the weather. Your chances of survival are usually much better staying in the shelter of your vehicle. I have never had to use it yet ( knock on wood)!!! But when you live out in the country there is alway the chance that you could end up sliding off the road and get stuck in the middle of a corn field. And it could be a long wait for help to come! Or worse yet hit a deer or something! So as they say, an ounce of prevention is worth a pound of cure! I give credit to my military back ground and two tours in Alaska to my attitude about being prepared! Especially in the winter!
We had freezing rain and sleet last night, I went to town yesterday and when I came out of one of the stores ( after spending close to an hour in it) I had over a half inch of ice completely coating my car! Starting around noon today it has been mostly sleet and snow with howling winds, I have some major drifts across my drive way, they say the worst is yet to come tonight! Here in the midwest they are comparing this storm to the one on 1978 or 1979, I missed that one, as I was in Germany at that time. But we had a do=oozy over new years of 99/2000 and I was stuck in the house for close to a week before they could get a grader from town to come out and clear our roads.
Stay safe and warm everybody!
