I grew up here and we NEVER had school closings because of the cold. Two feet of snow - yes, but not when it was zero degrees.
And to boot - we had to walk to school in those days, or wait outside for a bus. Nowdays more than half the kids are chauffeured to school by mommy or daddy.
We are turning into a nation of pantywaists.
My weather memory was trying to walk to school with sidewalks that were sheets of ice. I made it all the way to school without falling, over half a mile, only to slip on the front walk of the school.
