I chose that route as it is about 100 miles shorter than the "all freeway" route, and I knew it would be daylight. Going to KC I stayed on the freeway because I don't like night driving and two-lanes at night would be worse. Having driven it from Wichita to Tucumcari I would not do it again. Most of the way it is a fine road, but several slow downs and truly not much to see. I made good time and since I grew up in a tiny mid-west town there was much to consider as I passed through a few of them. It was like a trip back in time.Nice ride, when you went through Liberal,Kansas you passed within 30 miles of my house in Oklahoma. Yep very flat from Wichita to Dalhart.
I liked your breakdown chart as well. Good job
