Gas prices have been on a roller coaster ride in Southern California the past few weeks. From rock-bottom lows at the start of the year because of an abundant global supply, to a quick rise of a dollar or more per gallon because of a new summer gasoline blend and a refinery explosion in Torrance.

Nelson, who reports on transportation issues for the LA Times.
