As I recall, they lived near Pritchard, Nebraska, somewhere between Lincoln and Grand Island. Gus was a little dense in the head but lovable and liked farm life. The other boy wanted to be cool and hated farm life. The father wasn't too crazy about his father-in-law but put up with him. On one episode they went to Dodge City, Kansas, together to buy a bull calf. Brian Keith drove something like a 1959 Chevrolet or GMC pickup. Maybe it was the same one he had on Hardcastle and McCormick. Sometimes you wondered if the writer really understood farming. I remember one time they were going to harvest, and the father and his father-in-law got up early to get an early start, and they brought the whole crop in in one day!
