Might I suggest you start the route a tad differently... instead of turning left from Old Forge Road onto Mentzer Gap, continue straight and enjoy an amazing short trip up through the mountain. Passing the old forge picnic area, cross over the AT, turn left onto S Mountain road at the top, go past the S Mountain Restoration Center, and the National Guard station, then turn right on 233 across from the lily pad pond and a nice ride down to route 30 and continue on your trip as planned. Just a suggestion. That route is definitely filled with left, right, up, downs... Old Forge was closed to replace a bridge a couple weeks ago, but it's open now.
