Dad was an oilfield worker for Carter Oil later bought by Exxon. He worked near a very small town in southern Oklahoma names Wilson. Wilson's only claim to fame was that it was the birth place of Chuck Norris.
Thanks for the info. When he calls tonight, I'll be sure and ask him. His job takes him all over. He did a lot of work for oil refineries way back when. Have to see if he ever traveled to OK.
