I happened to have made the cardinal sin of leaving the night before on a buisness trip. I remember, or more to the point my wife reminds me, that my parting words were "Honey it's gonna be kinda slick tomorrow, I'd prefer it you didn't go out visiting". She left hours after I did and wound up sheltered at a friends house where I found her four days later.
My most vivid memory of the whole thing is standing out on the back porch and the absolute stillness. No noises, no movement, nothing. As though the world had ceased to exist.
