An interesting tour with a great guide (at least ours was, she shortened it to D, it was similar to Daenerys) that tells you the story of the gospel, in a historic and political journey through slavery, discrimination and a civil movement. Including Politics, social changes, community, music, and culture.
The gospel was boring but it is what it is. If you're more of a spiritual or religious person, or just enjoy seeing other cultures' customs (assuming you're not a black christian), you might enjoy that too. Anyway that part is at the end so you can skip it or leave before it ends.
