The city where bombings and marches helped galvanize America against segregation will mark the inauguration of the nation's first black president with a celebration Jan. 20. A national spotlight on Birmingham during inauguration day would be an invaluable promotion for the city, said Harriet Lessy, a Philadelphia-based public relations consultant. Lessy said Birmingham's activities serve a dual purpose of connecting local residents to a national event and putting Birmingham on the national stage with other major cities highlighted on the historic day.
