Not the one in the National Archives. I mean the area's weakness when a drop of snow hits the ground. Yesterday, hours before precipitation began, area schools preemptively closed left and right -- all that trouble for midday snowflakes turning to icy rain. And today, with blue skies, a forecast of 44 degrees, and the current temp hovering around freezing, Prince William County, Virginia, just added itself to five other counties taking the day off.
Growing up in Montana, without about an inch of black ice covering every road in town, school would not close. Your first-period teacher gave you a little leeway on the first snow day, to learn how to drive in the stuff again. After that, you were expected on time. In four years of high school, I can't remember school closing for weather. If we had the D.C. area's standards, we'd rarely attend between December and March.
