Long Island AVA: The Long Island AVA is an American Viticultural Area encompassing Nassau and Suffolk counties of New York, including the smaller offshore islands in those counties.  The AVA was established in 2001, over 15 years after two smaller AVAs were created at the eastern end of Long Island.  The Long Island AVA designation was promoted as a benefit for some wineries located just outside the two smaller AVAs and for wineries that wanted to create wines that use blends from vineyards in different parts of the island.  It was also developed and promoted as a consumer protection of the Long Island name; AVAs require that a minimum of 85% of the fruit used in the designated wine is grown within the borders of the region.  The "Long Island" AVA was authored by veteran Long Island winemaker Richard Olsen-Harbich who also authored the "The Hamptons, Long Island" and "North Fork of Long Island" AVAs in the mid-1980s.

Spinney Hills, East Quogue: Spinney Hills is in East Quogue, New York on the eastern end of the Long Island Central Pine Barrens region.  It is often used as a hiking, hunting, and off-roading area for dirt bikers, quadders, paintballers, and four-wheelers that includes miles of trails with near beach sand consistency.  Spinney hills gets its name because of Spinney Road, which used to connect the East Quogue side of the hills to Sears Bellows County Park and Flanders (home of the Big Duck) to the north prior to the construction of the Sunrise Highway New York State Route 27.  This region was created by glacial deposits of rock and sand during the last ice age.  The sandy soil also absorbs most rainfall so there are few ponds or rivers in the area.  There is a shallow glacial well in Spinney Hills known as an aquifer, which is where most of the rainfall in the region is stored.  These hills are the continuation of a long east west ridge of hills known as the Ronkonkoma Moraine, which form the 'backbone' of Long Island.  Much of this region is undeveloped other than a sand mine to the west and Southampton Pines to the east.  There have been large scale legal battles between private real estate companies and the Town of Southampton over the future of the area, being it is one of the last expanses of wilderness left on Long Island.  There is a very large native population of white-tailed deer in the region due to lack of natural predators.  In the higher elevations small sections of the hills have an almost alpine-desert look, with sandy open plateaus and extremely dwarfed vegetation .  The Dwarf Pitch Pine which dominate the region grow not much taller than twenty feet in height due to dry, nutrient-poor soil.  There is a desert effect in the Pine Barrens, with relatively higher daytime temperatures and cooler nighttime temperatures than the coast, only a few miles away.  There are spectacular views of the Atlantic Ocean and Peconic Bay from certain peaks in this region if one knows where to hike.  The consistent ocean breeze at the higher elevations passing through the long brushy needles of the Dwarf Pitch Pines creates a gentle whisping sound, or white noise, adding a peaceful ambience to the big skies and expansiveness one feels in this region.

East River: The East River is a salt water tidal estuary in New York City.  The waterway, which is actually not a river despite its name, connects Upper New York Bay on its south end to Long Island Sound on its north end.  It separates the borough of Queens on Long Island from the Bronx on the North American mainland, and also divides Manhattan from Queens and Brooklyn, which is also on Long Island.  Because of its connection to Long Island Sound, it was once also known as the "Sound River".  The tidal strait changes its direction of flow frequently, and is subject to strong fluctuations in its current, which are accentuated by its narrowness and variety of depths.  The waterway is navigable for its entire length of 16 mi , and was historically the center of maritime activities in the city, although that is no longer the case.
