I remember the blizzard of ‘78. My sister lives (and lived) on a side street on a hill in Queens. Her street was unpassable for weeks. Manhattan was plowed out in a few days. Congestion complicates things. One stuck car on a narrow street ties up traffic for blocks.
In ‘78 the streets were cleared (or not) by union civil servant Department of Sanitation drivers. The garbage trucks were repurposed as plows. The Sanitation drivers are incredibly unproductive, probably less than a fourth as productive as private contractors most other localities use.
Yikes!! Streets were impassable for weeks??
Were they able to get to stores? Did stores even have anything left?
Hope folks have prepared, accordingly.
