While fuel prices are a problem, a fuel shortage would be even worse. With the talk of a possible Iran-Israel conflict (in which case Iran threatens to close the Strait of Hormuz, interrupting 1/3 of the world's oil trade), I've begun to worry about how long I could operate if I couldn't buy gasoline tomorrow. Have any of you planned for this possibility? As a precaution, I added a few extra gasoline cans to my collection, so I should be able to operate for at least one week past "empty" (the point at which I regularly refuel) or over two weeks from "full". This "strategic petroleum reserve" would also let me weather a temporary price spike, like that immediately after 9/11 (on 9/12/01, the station down the street had unleaded for about $3/gallon--I'ld love to be "price-gouged" at that price now!). Any thoughts? Do you think one week of gasoline is enough? Or am I paranoid?
