Lexington, KY. We went there last October and circled Lexington. Varied terrain, but mostly rolling. Relatively respectful drivers if you're outside of Lexington, but beware of country dogs. We went just because one it was a ride in October and one of our favorite tour groups was guiding through the area. I really enjoyed the area. Prettier than I expected. Very diverse in all respects.

Asheville, NC? You have access to the Blue Ridge and Mount Mitchell (you said hills were OK ).
