is when you have to spend 45 minutes moving your car less than a block, from one unplowed side of the street to the other unplowed side of the street, because if you don't, you'll get a $35 ticket. And you have to do so when:
Temperature: 3
Wind speed 20-30 mph
Wind Chill: -19
Current Snowfall: 4-6 inches
Depth of drift holding door open: 18-20 inches
Signs of snow stopping: 0
The only silver lining I can imagine here is the fact that my apartment building is about a block away from a Rite-Aid. Granted, it's uphill, but then the return trip is downhill. Granted, I have to cross a major thoroughfare to get there, but when it's this bad out, I can move about as fast as the cars.
