Shrug - tell me what emergency fuel source you have control over?

If the power is out, can you get gas from the gas station? I think their pumps are electric, the credit card machine is electric, the cash register is electric.

Think of Katrina -- what fuel source was anyone in control over in New Orleans?

I lived on farms for years that had propane or butane for our fuel. This was in Texas, and we never had any storm or other event that kept deliveries from being made - no blizzards, hurricanes, or earthquakes. The guys came out in a truck and refilled our propane tank or butane tank.

My reason for suggesting that article is that a tank of propane won't go bad as fast as a tank of gasoline that sits out there for a year or two when I forget to siphon it out and use it in my car and refill the tank with fresh gasoline.
