Pretty much all the country south of PA is lovely. My dad was from upstate NY, and we made the drive from Louisiana to NY pretty much every year from infancy until I was about twelve, and not quite so frequently after his mom died. We took a different route almost every time, so I've seen most of TN, KY, VA, northern MS, AL, some of the Carolinas, and on up into Ohio and across. All that hill/mountain country is pretty.
And mom would say, "I keep telling you to ask for directions; but NOOOooo...!"
TN is beautiful country. I never met such lovely, friendly people. I thought I had a southern accent until I came across them, LOL.
