Hey y'all! In about a month I need to drive from San Antonio, Texas to State College, Pennsylvania. The current plan is to take I35 to I30 and I40, which will take me through Dallas, Little Rock, Nashville, Louisville, Cincinnati, Columbus, and just outside Pittsburgh.

It's a long drive, so I'm looking for a few places to stop along the way and stretch my legs. I know it's a large area and this is a very vague question, but does anyone know any particularly interesting places to stop?
