Driving home from work I saw some stations at $3.22 a gallon while two were at $2.83. The stations at $2.83 had cars 5 deep waiting for gas. The Wal-Mart near us was listed at $3.09 and had about every pump filled with cars taking on gas.
Why did it go up so fast? Iowa storage tank problems, Venezuela taking control of the last privately run oil field, a Chevron tanker attacked in Nigeria? Take you pick.
