Cora Hartshorn Arboretum and Bird Sanctuary

The Short Hills Park historic district is the oldest area of that unincorporated community in Millburn, Essex County, New Jersey, United States. It consists of roughly a thousand acres (4 km²) with 125 buildings, mostly homes, in the area developed earliest by Stewart Hartshorn, whose goal was to create an "ideal town" for living close to nature and the countryside on the 1,550 acres (6.3 km2) he bought in the area in 1877. Many of the streets follow natural contours, and Hartshorn routed them to leave as many trees standing as possible. It was added to the National Register of Historic Places in 1980. Millburn regulates development and redevelopment within it through a special section of its zoning. The average house within the district was valued at over $2 million in 2015.

The Hobart Gap is a pass and road through the Watchung Mountains in Northern New Jersey. During the American Revolutionary War, Hessian General Baron Wilhelm von Knyphausen attempted to seize the Hobart Gap, now crossed by present-day Route 24, in order to attack the American headquarters in Morristown for the British. He was met with successful resistance by General Nathanael Greene, and was eventually defeated by the Continental Army and the New Jersey Militia at the Battle of Springfield. For thousands of years the pass in the mountain range was an important aspect of the traditional Lenape Minisink Trail. From the pass, the trail led to a landing at the best place to ford what the Native Americans called the Fishawack (the Passaic River). The trail was a portion of the Great Trail and always had been used by the Lenape on their route to the Hudson River and south from their hunting grounds in what is now Sussex County. That traditional part of the Great Trail would become Route 24, and leads from the pass through Chatham, Madison, Morristown, Mendham, and Chester; it is called Main Street in all but Morristown, the county seat, which is dominated by a square in the center of its downtown. Route 24 was recently redirected around the old road in order to retain the historical downtowns of the colonial villages through which the trail led. The portion of the original path is now labeled Route 124.

Hogan made four bogeys at the first six holes and fell out of contention with a 76. In the final round on Saturday afternoon, Littler rebounded with a 70, but it was not enough. Furgol was helped by a great recovery on the 18th. After hitting his drive into the trees, he played his escape shot onto the 18th fairway of Baltusrol's other course. From there he managed to make par, carding a 72 for a 284 total. Mayer was tied with Furgol as he played 18, but he double-bogeyed the hole to fall into third.This U.S. Open was the first to be nationally televised, one hour of the final round, carried by NBC. It was also the first in which ropes were used to control the gallery, and prize money was increased by 20% over the previous year. This was the fourth U.S. Open at Baltusrol, but the first on the Lower Course, which later hosted in 1967, 1980, and 1993.
