The tour goes from one beautiful location to another, exchanging the sea for the mountains in gorgeous northeast Tennessee, just a short drive from the famous Smokies. At Kingsport, drivers will test their patience and their brake pedal in a concrete version of Martinsville Speedway where it’s ring-around-the-lightpole at both ends which are connected by wide, long straightaways. Do the locals show up the veterans or does a tour regular eek one out at the Concrete Jungle?
