I like the route currently near the border up to the above Lat and Long.
That way the rider gets to ride through elohim city and take a look at those funky cement sprayed structures and other stuff. Somewhere up there you ride over or next to workmens mountain. which was unique in that the road was just pretty much granite. Like you were riding on a huge monolith that had all the dirt washed off of it.
There is alot to offer up on this side of the state. I would defer my opinion to someone who knows it better. The highway in Arkansas was not really worth it under than a means of transit. I do not remember there even being many amenities along the way (gas, food, lodging).
