I don't think I had ever heard of a polar vortex before this year. And now we've been surviving through it. Crazy amounts of snow and cold, cold weather. The kids had an extra 3 days off during their Christmas vacation (that's 19 days off!) and then another 7 days off in a row because of it (in combination with a weekend). Roads were closing in all around us!
