Did the blue line your on the recommendation of a friend. Our driver was P, who was actually a trainee and it was his first day. He performed like a seasoned veteran. Great information, fun jokes, and a good ride. Even helped people take photos at one of the stops.
I will say that Obama's grandparents former house is one of those things you should have your camera ready for because it shoots by fast. Maybe it would be easier to take video and get stills from that.
