If you drop farther south through ILL you can see the Shawnee Forest, Garden of the God's, Cave in Rock where Tom Sawyer and Huck Finn floated the raft. You can cross the river at Paducah KY or ride the free ferry from Cave in Rock to Marion KY. West to East is the West Ky Parkway which isn't very busy, Hwy 80 is farther south but goes through the older smaller towns. Towns aren't far apart here and hotels are usually pretty easy to find. While in Lexington look for the Castle, it's near the end of the Bluegrass Parkway where it changes to hwy 60.
