I was driving with my brother, the preacher, and my nephew, the preacher’s son, on I-65 just north of Bowling Green when we got a flat. It was Sunday night and we had been to visit Mother at the Home. We were in my car. The flat caused what you might call knowing groans since, as the old-fashioned one in my family (so they tell me), I fix my own tires, and my brother is always telling me to get radials and quit buying old tires.
