One of the biggest perks of making a trip to Washington, D.C. is that a lot of the tourist attractions are absolutely free. The Smithsonian Museums and government building tours are great educational activities that never have an entrance fee.
Washington DC, also known as the Chocolate City, is closely linked to Black History. The District of Colombia (DC) has always been home to Blacks. Metropolitan DC and environs such as Mount Vernon, Alexandria, Arlington for example, have good representation of Black History.
