Back in the 70s, when the first big oil crisis hit (long lines at gas stations, rationing by license plate number, etc.), I had a friend who decided not to put up with those long lines.
He had a 500 gallon tank installed in his back yard (buried several feet deep), and had fuel delivered to his home by the same trucks that delivered to gas stations.
This was a guy who stayed pretty close to home (small town in the midwest), and never did any long distance driving, so one filling would last him a long time. The cost of the tank and associated pump was significant, but he had plenty of money (owner of a successful business) and just hated the idea of not being able to fill his tank when he wanted.
I often envied his maneuver, but that situation really didn't last all that long, and after I moved away I always wondered if he kept filling that tank or went back to normal operations.
