Dover Drag Strip, opened in May 1961 and closed in 1976, and was a dragstrip for quarter-mile drag racing in Wingdale, New York. The track was touted as "the smoothest, most state-of-the-art facility" of its kind at the time. The track featured epoxy-based asphalt, 60 feet wide. It had its own "timing tower" that had the timing equipment, and served as the operations center, with operators calling the Elapsed Time [ET] and MPH of each pair of racers via intercom to the "times slip booth" at the other end of the track. This is also where the track announcer entertained and informed the spectators of the action. All this was considered "new technology" in 1961. By 1964, the flag starter was replaced with a homebuilt "Christmas Tree", with multiple colored lights, counting down each start. This was one of the first of its type in the entire nation.The track was founded and operated by Brookfield gas station owner Chet Anderson and his partner, Joe Archiere, of Germantown, Connecticut. It filled the regional gap left by the closing of the Car Club Racing at Montgomery, New York, airport. Dover preceded the other tracks to follow suit, famous in the area, namely Connecticut Dragway (now closed) and the still operational Lebanon Valley Track, near Albany. Racers from as far as Maine, Massachusetts and New Jersey would regularly frequent the strip.Dover was host to exhibition runs by the Legendary Don ‘Big Daddy” Garlits, California's “T.V Tommy Ivo”, the original Batmobile and Jet Cars. Average car entries of over 400 were common with upwards of 4,000 spectators on special events. There has been continued interest in this now defunct track, thanks to the ongoing Dover Drag Strip Nostalgia reunion every year.

Wassaic is a hamlet and census-designated place in the town of Amenia, Dutchess County, New York, United States. As of the 2020 census, its population in 210. Located in southeastern New York in the valley of the Ten Mile River, Wassaic is bordered to the east and west by mountain ranges. The name of the hamlet is derived from the Native American word Washaic; "land of difficult access" or "narrow valley". However, Europeans found ready access by following the Housatonic River valley up from Long Island Sound and through the mountains along the Ten Mile River. One of the earliest recorded Europeans to settle in Wassaic was Richard Sackett. He petitioned the Colonial Government on March 11, 1703 for a license to purchase a tract of land in "Washiack". He was known as Captain Richard Sackett when appointed the first Dutchess County clerk in 1715.By the 1770s, Wassaic was processing Ancram pig iron into steel. This continued into the early 1800s, providing steel for the Harris scythe works at Hammertown, near Pine Plains in northern Dutchess. During the Revolutionary War, General George Washington marched through Wassaic on the way to Connecticut. Among Wassaic's main employers in the 19th century were Gridley Iron Works and the Harlem division of the New York and Harlem Railroad. In 1861, Gail Borden opened a factory for producing a condensed milk that would not need refrigeration. This was a welcome ration for the Union troops during the Civil War. Long sold by Borden, it is today marketed as Eagle Brand Condensed Milk. Wassaic was also known for dairy, sheep and grain farming. Wassaic is home to The Wassaic Project, a non-profit arts and music organization and the Wassaic Artist Residency. They provide summer programming as well as run an artist in residence program.

The Chapel of Our Lady of Mercy is a former Roman Catholic parish church under the authority of the Roman Catholic Archdiocese of New York, located in Clove Valley, Dutchess County, New York. The parish was established in 1885 and closed c.1947. By the 1880s, iron mines were operating at Clove and the Catholic families needed their own church since a trip of eight miles to St. Denis was a challenge, even if you owned a horse and wagon and many of the miners did not. In 1883 Father McSwiggan purchased one half acre in Clove. The chapel, named Our Lady of Mercy and seating about fifty at most, was erected, likely by the miners themselves by 1884. The Clove chapel, with its small steeple intact, stood on Dutchess Route 9 about 3.7 miles north of Route 55. Our Lady of Mercy at Clove was still functioning in 1945 according to the parish calendar for that year, but closed shortly after World War II.

Bull's Bridge is a single-lane vehicular wooden covered bridge across the Housatonic River in the town of Kent, Connecticut, close to the state border with New York. The first instance of a bridge at this location was constructed by Jacob and Isaac Bull in 1760, which gave the bridge its name. Popular legend suggests that George Washington crossed the bridge with the Bulls' assistance while still under construction. The current bridge was built in 1842 from timber, with additional supports added in the 19th and 20th centuries. Built with a Town lattice design, the bridge has reinforced trusswork visible on the interior. At the time of its nomination to the National Register of Historic Places the roof had wood shingles. It is historically significant as one of three surviving covered bridges in Connecticut, and was listed on the National Register of Historic Places in 1972.
