In terms of preparedness, one of the things I worry about is gasoline. I experienced the gas shortages of the '70s; it was not fun. Odd-even fueling days, no gas if you had more than 1/2 a tank, 10 gallons max otherwise, and sometimes spending over an hour in line for that.

I keep two 5-gallon jerry can's full of gas. Each month I dump one into the Jeep and immediately refill it, so the gas doesn't go bad. But I'd like to have more. I've been toying with the idea of getting a 55-gallon drum and a transfer pump, filling the drum 5-gallons at a time via jerry cans. I have yet to find out what zoning/fire laws might apply.

Assuming a closed drum of unleaded gasoline with the proper amount of fuel stabilizer, does anyone know how long gasoline can be stored before it becomes unusable? Would drawing-off and replacing 5 to 10 gallons a month make any difference?
