This photo taken May 20, 2014 shows a view of National Harbor from the top of the "Capital Wheel," in Oxon Hill, Md. With a massive new Ferris wheel overlooking the nation’s capital, a children’s museum, a village of restaurants and hotels and a major casino resort on the horizon, National Harbor in Maryland has quickly become a travel alternative to the marble monuments and museums of nearby Washington.
