I've about 100 gallons hoarded myself.
Just in case.
My wife does not drive that much (me not at all) just to the mall and back.
That ought to be enough for several months of autonomy !
Maybe even up to the 2024 elections ?

And anyway, we just keep replenishing it . . . one gallon goes . . . one new gallon joins the family !
We have these jerrycans . . .
