Atlanta is the cradle of the civil rights movement, and the National Center for Civil and Human Rights gives the city a museum that tells its story.

Exhibit designer David Mandel said the average visitor -- the "stroller" -- will spend 75 minutes at the center. (Less for "streakers," more for "scholars.")

Compared to more lighthearted attractions nearby, such as the Georgia Aquarium and the World of Coke, the downtown Atlanta museum offers more serious fare: scholarship, a walk-through history and some consciousness raising.
