Based on a single experience....
....of helping a young woman student from Tennessee whose car was stuck in a few inches of snow in Colorado many years ago (she thought it was a good idea to rev her engine up to high RPMs despite having no traction on any of her car's non-snow tires), I'd say most folks from Tennessee, outside of the hillier region in the east end of the state, see snow so rarely they suffer temporary insanity when it starts falling.
