I'll never shake my head & laugh at hubby again for insisting that we keep several 5 gallon fuel cans filled, we have a rotation system for using them to keep the fuel rotated. Yes, this includes diesel for the tractor at the farm. He also likes to keep all of the vehicles parked near full in case something should happen & we need to escape to the farm for days.
I used to think he was just overly paranoid, but I'm starting to think that it may happen some day. Fortunately, I have a habit of keeping the car gassed, I just hate having to stop at the gas station before I go somewhere.
