Agree. I was excited that I had an upcoming business trip that involves a 3-hour drive. Listened to a lot of it on the drive. Very well done. If you want some reading that is related, but not exactly the same, I recommend:
1) "Barracoon: The Story of the Last 'Black Cargo'" Zora Neal Hurston - NOTE: If you've ever noticed Africatown at the base of the bridge that crosses Mobile Bay north of the tunnel, you will know why it is called that.
2) 1491: New Revelations of the Americas Before Columbus by Charles C. Mann
Both are very good reads.
