My cousin Andrea, who lives in my home town of Washburn, Maine, took these pics at 7:00am (EST) this morning at her house. Now that's cold!
Today, schools in Williamson County, Tennessee are closed because it's too cold! The temp? 7 degrees/-3 windchill as of 8:00am (CST).
By the way, schools in Washburn are open today! They're tough up there. When I was a kid we used to walk to school in those temps... up hill, both ways, in four feet of snow... and we loved it! ;-)
