I remember how shocking it was the first time I saw Los Angeles-area gas stations advertising prices at $3 per gallon--this was about a year ago, in May 2007. Just today, barely eleven months later, I drove past a station at which the price for their premium fuel was over $4!! (The photos associated with this article were taken today, at several stations in the San Fernando Valley.)

Hey, it's Earth Month, have you heard? Thank goodness we only have to think about the little rock we cling to that sustains our lives for one month out of the year. In May we can move on to my favorite, Asteroid Belt Month.
