That is true.
We got a small taste of life without electricity here in NY after the hurricane. We were without power for 11 days. Fortunately , not much damage... many others suffered far worse. We have a generator, but ran out of the propane to power it after 8 days. We couldn't get a refill since the demand was so high, there were not enough delivery trucks.
You probably saw the problems we had with gasoline delivery too, due to damage to the ports and pipelines, and the fact that the gas stations had no power.
After the generator ran out of fuel, we left to go to my in-laws 2.5 hours away , takinbg all my insulin stockpile with me to keep it refrigerated.
All the perishable food in the grocery stores had to be thrown out...and the storm wa sso widespread that most of the stores were closed.
