Same here, I have half a tank, if I recall everyone rushed to fill their tanks after 9/11 after everything calmed down it went back down. We went from 2.74 to 3.30 although some stations are still selling at 2.74 but the lines are long!
I have 3/4 of a tank, but I only use a tank a month. If I walk to my local supermarket and only hit the post office 1x aweek to ship the stuff I sell, I have enough gas to keep me up and about town probably well into October.
