re: Most boring drive in America

West Texas is horrible. Lots of nothing for long stretches at a time.

I-55 between Jackson and Memphis is incredibly boring. Nothing but trees and gently rolling hills. Very few interstate exits have anything. I-55 between Memphis and St Louis is just as bad, but the terrain is completely flat and void of any trees.

I-40 through most of Oklahoma is boring as frick.

Whatever it is that goes between Indianapolis and Louisville is pretty bad as well. There's one exit with a trashy outlet mall that comes out of nowhere. That's your break from endless boredom.
