Never been in/near Knoxville before. We (2 - 56 year old ladies) will be going there mainly to stop by at the Andrew Johnson's grave site (scrapbooking) in Greeneville, TN. Question - is it worth staying in Knoxville a few days (driving to Greeneville and back)? I'm not sure what is there to do. Or should be go someplace else (we'll be heading toward home - Chicago) near Greeneville that is worth stopping by for a few days. We're in no hurry getting home so time is not a factor.
