Listening list

Hey folks — I'm taking suggestions for audio books to digest during the upcoming trip. When I did the Mississippi trip, I listened to Jon Krakauer's Under the Banner of Heaven a couple days after leaving Navoo, IL, which was a bit surreal. I would have kept my guard up if I'd known.

Anyway, that was a great road book. I think I'd prefer non-fiction, and it should be something pretty lengthy, but not too deep. I was contemplating Picketty's book, but I don't know that I'd be able to hang while laboring up hills in the blazing heat.

So, hit me. Whatcha got?

P.S.: I know audio books are cheating, but surely you don't expect me to ride and read at the same time, right?
