Turns out that work was cancelled due to snow.  We're expecting 6-9 inches,
and it just started to flurry as I started home.

However great it is to get out of work due to snow, it's an equal magnitude
of great but opposite in direction having to drive to work the next day.  No
matter how much they plow, it's always a bit scary.

I guess there's a conservation principle in here: Conservation of Suckage.
Probably a symmetry in the Lagrangian of life nobody's observed yet.

I'll try these great ideas either on Friday or Monday and report back.

Pete
