an out-wash plain and becomes largely rural (and enters the Town of Southold), with an economic stronghold on agriculture, particularly in the shape of wineries and vineyards. This recent trend, beginning in the 1980s with the conversion of potato farms, has given the North Fork the distinction of being the most productive agricultural area in New York State. Despite this, North Fork, contrasts starkly with the more populated and more well-known South Fork's Hamptons. The North Fork terminates at Orient Point, where the Cross Sound Ferry Company has a terminal for ferries bound for New London, CT. and Block Island, RI. Greenport, a village in Southold midway between Orient and Riverhead, is a major economic center for the North Fork and as such, is the eastern terminus of the Long Island Rail Road's Main Line. The North Fork is also geographically tied to a separate township, Shelter Island, an island in the Peconic Bay accessible via ferry that leaves from Greenport, adjacent to the railroad station. The island also has a ferry on its south side that connects with North Haven on the South Fork. In popular culture In literature, the North Shore is the setting of F. Scott Fitzgerald's 1925 novel The Great Gatsby, which centered on the area's wealth and the aspiration of the title character to be accepted into its high society. The novel's "West Egg" and "East Egg" were fictionalized versions of the real North Shore villages of Kings Point and Sands Point, respectively. The Gold Coast by Nelson DeMille is a novel set in the area. The distinctive upper class speech pattern known as "Locust Valley lockjaw" takes its name from the North Shore's Locust Valley area. The aristocratic cachet persists despite suburban infill converting much of the North Shore into commuter towns.
