Boise City has to be included instead of Guymon it's the one city that connects between Texas state line and Colorado along with New Mexico at a roundabout in town square also it has some awesome lil landmarks!
Such as the the life size long neck Dinosaur just outside of town and the accidental bombing of Boise City OK historical marker, with the little Bomb statue on the sidewalk where the roundabout is. it's one of those small towns that should be apart of the bigger picture imo. It Also has a Loves Truck Stop.. so it would be great to include a hearts there Below is my bit of research online and what I've seen myself in person!
