We pulled off I-57 at Dix only to find that the antique shop no longer exists. Back on the road, up to speed, and two minutes later a white Explorer flies by in the passing lane. I noted a Purdue logo on the right rear quarter-panel, then espied a Texas license plate. "It's your granddaughter!" I shouted. Quickly overtook them, slowed again. As they passed the next time, honked and got their attention. Five minutes later, we pulled into Mt. Vernon where the five of us had a nice visit at Arby's. (The manager did not kick us out, but allowed that we were a little loud!)
They back on the road toward Texas, we checked into hotel. Looking forward to reunion tomorrow!
