I checked back with the tire guy and he was lightly grinding the inside of the tire where the leak had been. I wondered what had made the hole and he replied, “I think it was probably this” as he held up a thin sliver of steel. “Looks like part of a key or something.” As he handed it to me, I slipped it into my wallet as a souvenir. Soon the tire was repaired and mounted back on the Jeep. I asked the tire guy how much I owed him. “You gotta pay inside” he said. I gave him five bucks, shook his hand and thanked him. Inside they charged me eighteen dollars for the repair. Pretty darned good deal. We pulled out onto Highway 12 repaired and raring to go.
