I took a 340 mile ride today. Ride down to Zanesville and headed down 555. It was actually pretty clean. Took it to it’s end outside of Belpre. Had Subway in Belpre. Headed north on 339-60-83-78-216-93 and then 668.
I just found this on motorcycle roads. It’s a list of the best routes. It ranks the triple nickel as number 8. Not sure about that, but it is pretty good road.
