The worst snow drive I ever made was from Florence, SC to Detroit, MI January of 1996 through the blizzard. It was longer than 24 hours to get to Detroit, by way of Cleveland, though I am not sure the total road time. I drove my mother's car for her, we had a cat and dog in the car and my father was in the 24foot rental truck ahead of us, which is the only reason we made it. The WV Turnpike was closing to traffic while we were on it, and we rolled along at 20MPH with him grooming the path with the truck. When we stopped to clear things we just stopped. No need to pull over.
