New York is a dynamic and uniquely dazzling state. Its exciting New York City is one of the most famous cities in the world. With a thriving business climate, a highly exuberant cultural and artistic atmosphere and spectacular attractions such as Times Square, the Statue of Liberty, and Central Park, residents of the Big Apple experience the nuances and opportunities of one of the world's grand metropolises. But the state is home to much more than the Big Apple. It is one of the most economically progressive and culturally diverse states in the country and millions of visitors a year are attracted by the state's romantic Niagara Falls and the fishing hideaways of the Finger Lakes region and the great Hudson River. Additionally, the Empire State is a national leader in education and invests generously in its more than 4,000 public and 2,150 private schools. Eighty percent of graduating high school students statewide seek postsecondary education. New York's borders touch (clockwise from the south) two Great Lakes (Erie and Ontario, which are connected by the Niagara River); one former Great Lake (Lake Champlain); the provinces of Ontario and Quebec in Canada; three New England states (Vermont, Massachusetts, and Connecticut); the Atlantic Ocean, and two Mid-Atlantic states (New Jersey and Pennsylvania). In addition, Rhode Island shares a water border with New York. New York is also the site of the only extra-territorial enclave within the boundaries of the U.S., the United Nations compound on Manhattan's East River. The southern tip of New York StateżNew York City, its suburbs including Long Island, and the southern portion of the Hudson Valleyżcan be considered to form the central core of a "megalopolis," a super-city stretching from the northern suburbs of Boston to the southern suburbs of Washington D.C. in Virginia and therefore occasionally called "BosWash". First described by Jean Gottmann in 1961 as a new phenomenon in the history of world urbanization, the megalopolis is characterized by a coalescence of previous already-large cities of the Eastern Seaboard: a heavy specialization on tertiary activity related to government, trade, law, education, finance, publishing and control of economic activity; plus a growth pattern not so much of more population and more area as more intensive use of already existing urbanized area and ever more sophisticated links from one specialty to another. Several other groups of megalopolis-type super-cities exist in the world, but that centered around New York City was the first described and still is the best example. While the state is best known for New York City's urban atmosphere, especially Manhattan's skyscrapers, most of the state is in fact dominated by farms, forests, rivers, mountains, and lakes. New York's Adirondack State Park is larger than any U.S. National Park outside of Alaska. Niagara Falls, on the Niagara River as it flows from Lake Erie to Lake Ontario, is a popular attraction. The Hudson River begins with Lake Tear of the Clouds and flows south through the eastern part of the state without draining Lakes George or Champlain. Lake George empties at its north end into Lake Champlain, whose northern end extends into Canada, where it drains into the Richelieu and then the St Lawrence Rivers. Four of New York City's five boroughs are on the three islands at the mouth of the Hudson River: Manhattan Island, Staten Island, and Long Island. "Upstate" is a common term for New York State counties north of suburban Westchester, Rockland and Dutchess counties. Upstate New York typically includes the Catskill and Adirondack Mountains, the Shawangunk Ridge, the Finger Lakes and the Great Lakes in the west; and Lake Champlain, Lake George, and Oneida Lake in the northeast; and rivers such as the Delaware, Genesee, Mohawk, and Susquehanna. The highest elevation in New York is Mount Marcy in the Adirondacks.
