Route through Oklahoma
I should hav mentioned that I took US 259 north from the Longview, TX area. The Texas portion was wide and smooth. When I crossed the Red River into Oklahoma, the first miles were pretty bad (rough, narrow, and curves) until I reached Idabel. From there, north, the roads were very good.
From Poteau, I swung over to Sallisaw since I was going to the Cherokee Land Airstream Park. On the way south, I took I-540 and US 271 through Fort Smith to Poteau to rejoin the route.
