Our Christmas trip to Grandma's house in WV took just over 9 hours, because the weather cooperated with our travel plans. Not so much for the trip back to NH. Misty rain and thick fog, slowed us down early in the trip, and heavy rains slowed us down for the rest of the trip. Took us over 13 hours to get home. At least it wasn't icy -- just took a long time.
@therubysusan Thanks. This wasn't the worst mountain. I have another pic where the semi right in front of us is disappearing into the fog. But, because of the semi, the windshield is so messy, it's not a good picture.
@joansmor The back road are quite spectacular, and scary for people who aren't used to mountain roads.
