The truck ended upright after what I'm sure was a horrible experience. The guys that were there when I stopped to take the pic said the driver apparently fell asleep, (this happened Monday evening) woke up and cut the wheel sharply; then hit the guide rails, over the steep embankment he went( it doesn't look steep in the pic but take my word, it is! Go ahead and enlarge.) I'm not much good judging how far; but this driver must have ventured down about 40-50 feet, almost into Two Lick Creek below. Glad to say the driver is fine with multiple bruises and mighty stiff. The right side of truck had most of the damage.
