As a former Yankee living in the South, I often feel the need to apologize for the amount of things I don’t know about Southern culture. Things such as the shoe size of the quarterback of UT's football team, or how to fry catfish fillet. What is a catfish? Does okra grow on trees or bushes? I don’t know. The good news is that native Alabamian Rick Bragg, author of books such as The Prince of Frogtown, All Over But The Shoutin’, and Ava’s Man, does know where okra comes from.
