Actually, he's a neat guy. A real showman in the classic throwback sense. Former cop, compelling speaker. Books: In Search of the Lost Ark of the Covenant; In Search of The Mountain of God (his best); In Search of the Lost Mountains of Noah. (Full disclosure: he's a friend of mine.) He's genuinely driven to follow Scriptural clues, and his presentations center on the literal reliability of the Bible. I agree with him that often scholars and experts lose sight of the plain meaning of the text.
In Search of the Mountain of God is an excellent book. I've just seen a lot of refutations of Bob and wonder how much of what he sees is a result of what he wants to see.
