I-77 Between SC And OH in January - What to Expect?

Be aware that you have a big grade at Fancy Gap at the border of NC and VA. It's 4%-4.5% for 6.5 miles.....and going north that would be up hill for you. It's one of the longest grades in the whole interstate system. 77 through West Virginia is hilly and twisty too. Any snowfall would concern me although the interstate is usually very well maintained. It's also a toll road in WV. Depending on the weather boring 75 might be the safest route if you are towing.
