Where to go on vacation...?

The rental car is lined up. I have next week off. The only remaining question: Where will I go on my vacation?

I'll decide Saturday after intense consultations with The Weather Channel. My choices are:

Dallas to Memphis, Chattanooga, Franklin NC, Radford VA, Kingsport TN, Nashville, Lexington KY, Frankfort, Louisville, St. Louis, and back home;

Dallas to Wichita, Lincoln NE, Pierre SD, Norfolk NE (Johnny Carson's hometown), McCook NE, then back through KS and OK to home;

Dallas to St. Louis, Springfield IL, Indianapolis, Kokomo, then up into Michigan, Dayton OH, Columbus, Frankfort, Louisville, St. Louis, and back home.

Any suggestions from you guys?
