Amarillo South on 287 to 35 then straight on to Dallas.
And every small town in Texas has a Dairy Queen but that one in Clarendon, if I remember correctly is right on the road. Easy parking.
I researched that area when we were looking to buy a house. It was the wind that decided us but it seems where we did buy, we missed the signs "Beware of Blowing Dust."
I also drove semi, irregular route team driver, so I have waltzed across Texas, hammer down, many a fine day and night. (Texas is a long ways from here to over there, yes indeed.)
