The natural gas explosion that occurred near Palo Pinto, Texas, at 1:45 am on December 16, 2005, Texas, is kind of like my "Pearl Harbor" or maybe the "Alamo" would be a better metaphor. Palo Pinto was the touchstone that went unheeded.
The explosion "left a crater 250 yards wide and about 30 feet deep", according the local fire chief. Car-size rocks were blasted into the air. The ensuing fire burned over a square mile.
