Most of the roads on this ride are excellent. Route 302 had some traffic but the other roads have very little. I went long stretches at times with seeing no cars. The Kinsman Notch section has a 13% grade going up, and 9% going down. Route 117 (Sugar Hill Road) is quiet and picturesque.There’s a fairly significant climb on 302 coming into Bethlehem from the western side, with a steep descent.
