This makes me smile - I lived in NoVA for over 20 years, and am well aware that 1 inch of snow causes complete paralysis! I also remember that storm 25 years ago, as I had to drive on Route 50 (VA), which hadn't been plowed, was full of icy ruts over a foot deep and littered with abandoned cars. (Crazy, I know, but I was taking an evening class at GW and my prof, who lived in Alexandria, insisted on going through with it even though *he* had to drive home, too...)
I wonder if they'll ever be properly prepared for snow in D.C.
