I about shat myself....most terrifying two and a half hours ever - from just inside the OK/TX line all the way to just outside Amarillo. My sore knuckles didn’t recover for two days.
Reminded me this pileup, that occurred Thanksgiving 2012 outside of Beaumont. As I recall, the fog just came out of the air, literally.
