I remember when some people with money bought underground fuel tanks and paid to have the tanks buried and filled with fuel on their property.
Also, people drove around with cans of gas in their car trunks, and sometimes in rear end collisions everyone was cremated.
Also, the fumes from the gas cans in the trunk would overcome the drivers and they would pass out at the wheel.
I remember being on a weekend jaunt to Michigan in the winter and on Sunday afternoon there were no gas stations open, but I found some at an Ohio Turnpike rest stop.
My dad looked into getting a 50 gallon barrel and stocking up on gas for emergencies, but half the problem was being able to find a place that would sell you 50 gallons!
