We couldn't drive through Tennessee without a return visit to the Lane Motor Museum in South Nashville. They have a splendid collection of vintage vehicles, including microcars, which they strive to keep in full running order. I love their barrier-free exhibits. Makes taking photos and closer looks at details and interiors easy. I'm dangerously close to doing my "happy dance" in public as I get to have my photo snapped in this Citroen 2CV.
Before heading north-east into Kentucky will fill up on diesel which at $3.41 per US gallon is the cheapest this tour.
