One journey that is enjoyable is following the Old National Road, aka US 40. For one thing, you are not on an interstate! Anyway, near Brownsville, Ohio, east of Columbus, you’ll find the Eagle’s Nest Monument. It was erected around 1916 after a 29 mile stretch of the then unimproved and often nearly impassable road was replaced with concrete. The stretch of highway ran from Zanesville to Hebron. The large granite rock has some great markings, including a rough Conestoga wagon.
Get off the interstate and travel the Old National Road anywhere along the route in any state. The signage is excellent and easy to follow, and you won’t be bored!
