Need help quick! Road trip tomorrow!?

I'm leaving for a road trip tomorrow from Lexington, Ky to Memphis, Tn. I was wondering if anyone knew of any sights along the way (specifically for the Nashville to Memphis stretch of the trip) or any good restaurants along the way. I'm a horrible procrastinator so I do need answers asap! Thank you all and as always, 10 points for the best answer! Oh and while this question is up, I'm going to keep looking online for things, so if anyone even knows of a good site that lists things to do along the way I definitely want those sites too. Thanks!
