New York is the largest city in the United States, with the city proper's population more than double the next largest city, Los Angeles (or roughly equivalent to the combined populations of Los Angeles, Chicago, and Houston, the United States' second, third, and fourth most populous cities respectively).
Comprised of 2.6 million acres in the Adirondack Forest Preserve and 286,000 acres within the Catskill Forest Preserve, these lands represent a majority of all state owned property within the Adirondack and Catskill Parks.
In May 1966, the Sunken Forest Preserve, Inc. donated the property to the recently established (1964) Fire Island National Seashore, under the condition that the property shall always be maintained in its natural state and operated as a sanctuary, and that no public road or highway shall be built through it.
