1973 oil crisis. I remember how upset my folks were when gas went from 21 cents to over 50 cents per gallon. My numbers could be off but should be close.
That is how I remember those days. We had an odd even system. If your tag ended in an odd number you got gas (10 gallon limit) on Monday, Wednesday and Friday. If it was even you were allowed to purchase on Tuesday, Thursday and Saturday. All stations were closed on Sunday. Lines were literally around the block and tempers were short. Real short. People got shot and beat up all over the place.
It was pure hell. A lot of us car pooled for the first time in our life. We had four in our car pool. I still wonder if there was really a shortage. .
