Our buddies at BuzzFlash have begun a great series on what happened when the Exxon Valdez created one of the worst non-natural environmental disasters in history. Hard to believe it's been 20 years since I willingly bought gas from Exxon. I think I've stopped at Exxon about a half dozen times in 20 years, and only because my car was running on fumes, and it was my only choice. I still avoid them, much as I avoid Wal-Mart.

Anyway, check out their series here…
