In the U.S., West Virginia is associated mainly with forests, the heroin epidemic in its cities and its backwoods population, who refer to themselves as hillbillies. West Virginia is definitely not associated with environmental protection. "Rolling coal" is a popular hobby in these parts - it involves removing the particulate filters from a diesel pickup truck, driving to the nearest city, waiting until a Prius or a cyclist goes by, gunning the engine and roaring off, leaving a cloud of foul-smelling exhaust in its wake. That's what passes for humor in West Virginia.
Plenty offensive.
