Washington, officially the State of Washington, is a state in the Pacific Northwest region of the United States. Washington is the only state named for a president. It was nicknamed “The Evergreen State” by C.T. Conover, pioneer Seattle realtor and historian, for its abundant evergreen forests.
Forests cover about half the state's land area, mostly west of the North Cascades. Approximately two-thirds of Washington's forested area is publicly owned, including 64 percent of federal land. The state's various areas of wilderness offer sanctuary, with substantially large populations of shorebirds and marine mammals. The Pacific shore surrounding the San Juan Islands are heavily inhabited with killer, gray, and humpback whales.
Monuments and memorials, eclectic neighborhoods, true local flavor – Washington, DC is a place unlike any other. It’s your home away from home with free museums and America’s front yard. There’s nothing quite like the Smithsonian Institution, a collection of 19 behemoth, artifact-stuffed museums, many lined up in a row along the Mall. The National Air & Space Museum, National Museum of Natural History, National Museum of African American History & Culture, Reynolds Center for American Art & Portraiture – all here, all free.
The president, Congress and the Supreme Court are here, the three pillars of US government. In their orbit float the Pentagon, the State Department, the World Bank and embassies from most corners of the globe. If you hadn’t got the idea, power is why Washington emits such a palpable buzz.
