You might consider this map concerning Route 66, it's not quite right though on the section between Joplin and Halltown on the way to Springfield. For all practical purposes the section between Carthage and Phelps is correct but between Phelps and Halltown there are parts of the original narrow 66 that isn't on that map. I could meet you in Joplin and show you what I mean.
