I've never been, but I saw a documentry (SP?) on his show. You'll need to bring a list of everyone in your family that has passed. When you're put on the spot, if he's referring to you, it might be hard for you to think clearly. They suggest that you bring your family tree. Also, you might want to bring a lawyer for the extensive contract you have to sign (j/k). John Edwards has the biggest release form in the tv buisness. You're not allowed to talk about certain things that go on there. It's kinda like the contract that David Copperfield's employees and assistance have to sign so they don't give away the secret of the illusion.
