@kel No kidding. I was in emergency service response (CPS) in FBX when it was -55° with ice fog. Stay off the road so those who HAVE to go out can do so without worrying about another person in crisis.
Friends are upset about plane cancellations. Better alive at home than dead from icing on the wings. You can visit later because you'll still be alive.
If you lose heat call emergency services to get to a warming shelter.
Lots of people die in weather like this.
