It would be a very scenic ride - indeed borderline spectacular, up the Delaware Valley and Gorge though. The very thing that makes it excruciatingly slow. I have driven on the parallel local roads often as a slow scenic diversion away from somewhat scenic Rt 17, on the way to or from the Deposit area where I headed north to visit my old host family at Otego, usually via Franklin and then down the escarpment into the Susquehana Valley, or straight to Sydeny and I-88. I can almost claim it to be my old stomping grounds.
Incidentally, the shortest route to Otego from NJ is up Rt 17 to Roscoe and then on little mountain roads to Franklin and then down into Otego.
