Somewhere along I-40 (Old Route 66) in Texas panhandle between Amarillo and New Mexico boarder. Next to the grain elevator is a smaller building with the Texas flag on one end. This picture was taken at 70 mph or so out the car window. Just off the highway you may notice an indentation in the grass this is the old Route 66 which is now covered in grass (between the car window and the KOA sign). Much of I-40 runs along the old Route 66 from Chicago to L.A.
KOA sign: "Tucumcari 62 miles"
