We have another case of animal arson — this time a cow is the culprit. No, it was not Mrs. O’Leary’s cow. And we’re not referring to the 293-acre “Cow fire” near Ukiah, California, it was the 35-acre “Green fire” near Big Sur, California. Both fires were recently contained, but investigators have concluded that a bull on the El Sur Ranch rubbed his horns and back on a power pole until it fell. The lines arced, starting the fire.
