Mason-Morrow-Millgrove is a brilliant clean river-sweeping road from South Lebanon until 123. Beware spirited riding between 123 and Stout road. I encountered a fair amount of gravel in my recent travels. One of my favorites; Corwin Road to Corwin. A quick left then right at the church gets you on New Burlington rd, west to Wilson, Right on Roxanna New Burlington, and that takes you to 380 which is a smooth ride back to 73/71. You're surrounded by 48, 73, and 380, which all lead back to civilization.
