Originally from a small town in North Carolina, Luke left his family farm at age 20 after his father died and hasn't returned. His sense of humor rivals the day in day out work of caring for horses as he jokes about being kidnapped by a pretty woman and never returning.
He doesn't leave the ranch very often, in fact he says he would like to drive in to San Antonio (45 minutes down the highway) to see his old friends but that that would cost him too much in gas, and he just "don't" have the time or money for that. With a heavy draw of a southern accent, he fits right in this scene and for the last 25 years says he is happy to be doing what he does with the horses - making sure they're alright.
