Best tips for surviving a "Polar Vortex" winter

What I've learned about surviving a Polar Vortex winter

This winter of record setting low temperatures, including numerous snow storms and dozens of days in the single digits, I've learned that...

-Bundle up and get some fresh air- I've found it's not ACTUALLY as bad out there, often, as I thought!
-once you get your body moving, indoors or outdoors, you will be much more comfortable.  Don't curl up like a turtle and be still.  Move around and exercise and warm up your body.
-turn on that fireplace and enjoy!
-use a microwavable warm pack (rice and spices sewn up in cotton sock is simple one) for your feet in bed or to warm up anytime
-avoid extra warm showers because it dries out your skin (ironically)
-keep a shovel in your trunk and by your driveway!  ALWAYS have gloves (and chapstick and kleenex!) in multiple places so you will never be without when you have to shovel your car out a rut
-yes, you CAN drive on the streets when school is canceled!  It's not as bad as they think, often!
-time to get creative about playdates (without driving), activities and action (without going outside)
-Gotta get one of those adult snow-suits which includes hood, coat, and pants, like my neighbor with kids has!  She can go outside any time.
-It takes at least 5 minutes longer to get ready to go anywhere...
-Keep the pediatrician on speed dial!
-Still thinking of more to add...
