I do know what a clodhopper is, as i grew up on a farm in Mississippi in the 40 and 50 i have hopped over a few my self. Sure am glad i don't have to do that again.
On your trip to Tn and Ky you may want to think about driving the Natchez Trace parkway from Natchez, Ms to Nashville, Tn really is a great drive and they don't let any 18 Wheeler on it.
