Most of the people who are alive in this country today are fortunate to have never experienced any form of rationing other than having a limit on sale items at a grocery store; first three with coupon.
Oddly, I feel fortunate to have actually experienced rationing on the East Coast in the 1970s. Yes, it was strange that you were only allowed to buy gasoline on even days if your license plate ended in an even number, or at other times allowed to purchase five gallons. It was a serious shortage and we lived with it and found ways to wiggle around it.
One way was to always have a police scanner on because the gas stations would alert the police when they would be opening. The police needed to be there for crown control for bad tempered customers and to be the last car in the line when the station was about to run out. Once you heard on the scanner that a station was going to open you ran out the door and got to the station before the line formed. Once five cars were lined up all cars in the viewing distance would stop in their tracks and join the line.
You were very fortunate if you could actually hit three station openings in one day. Some people would fill up cans with their allotment and sell the gasoline on the black market. Most people had private sources. Some people would drive 30 miles up the New York State Throughway and turn around to hit the no limit station on the way back.
With this experience in my past I wonder if people could survive any rationing these days. Can you imagine the craziness that would surround a present day gas ration, or worse yet food rationing? During World War II just about everything was rationed. Every person made an effort and went without to support the war effort. Imagine how quickly the present war we are in would end if rationing were imposed on the average American citizen today.
