These surveys are bullshit.

CAMARILLO, Calif. – U.S. retail gas prices dropped 15 cents a gallon in the past two weeks, the sharpest decline in nearly a year, according to a survey released Sunday.
(…)
The lowest price was $2.60 a gallon in Des Moines, Iowa, and the highest was in Honolulu at $3.32.

I guess they didn’t survey Rockville, Maryland, last Friday when I tanked up our rented van at $3.39/gallon.
Six hours later, in Beechwood, Ohio, I tanked up again…for $2.69/gallon. And on our way home two days later, I bought another tank at $2.57/gallon just north of Columbus.
Highway fucking robbery going on in Rockville. But I guess those rich bastards can afford it.
