"Two years ago, Richmond, Va., installed 17 markers delineating a slave trail, running past the sites of slave markets and a slave jail."

"A national slavery museum is being planned, said Delores McQuinn, a state legislator, who has led the slave trail project. Charleston, S.C., has moved away from its traditionally genteel approach to antebellum history to one that acknowledges the central role of slavery in the city’s development. An International African-American Museum is planned there as well and is seen as good business."

"Tourism audiences are changing," said Mary Battle, a public historian with the Avery Research Center for African-American History and Culture at the College of Charleston.
