It is in a rectangular clear plastic container. It contains a small notebook, crayons, and some fun loot for you to take and replace with something fun.
Enter Ward Acres on Broadfield, and make your way past the doggy park and the community garden. You will then walk behind the old stable buildings of Hillandale Farm. Continue along the marked trail and you will stumble upon the Mr Dickerman's horse cemetary. The cache is located somewhere along the nearby stone bridge.
According to Wikipedia:
Ward Acres was originally part of the estate of Watson Dickerman. Born in 1846 in Mount Carmel, Connecticut, Dickerman bought property on Quaker Ridge Road in 1884 for breeding 'American Trotters'; he named the estate "Hillandale Farm". Over the years he added to his estate until it reached nearly 500 acres in Mamaroneck and New Rochelle.
His son Watson P. Dickerman became well known in horse breeding circles for his elaborate stables and for his two great sires; "Bellini" and "Atlantic Express". The tombstones for some of Dickerman’s famous standardbreds including: "Ethelbertha", Grand Dam of Bellini (1881); "Merry Clay", Dam of Bellini (1881) and "Bellini" (1887) are visible along one of the trails within the park.
Dickerman died in 1923 leaving the bulk of his $5,000,000 estate to his wife who then sold a large portion of the land to the Ward family in 1925.
Between 1945 and 1953 the stables and barns on the estate were renovated by William’s son Jack B. Ward who took a great interest in the property and founded the "American Saddle Horse Breeding Company". Jack’s endeavors were rather successful, with his horses winning hundreds of ribbons. His horse "Hickory Mistress" alone won 21 ribbons in 1847. The enterprise continued until 1957.
In 1949 Jack proposed a plan for a 1,000 seat theater, a museum, and a restaurant on the property adjacent to the barn structure. The theater was to bring projected Broadway productions to New Rochelle for two week tryout periods. The plan was voted down by the City Council in 1949. In 1956, Ward did start a motion picture company at 435 North Avenue known as Ward Acres Studios. He advertised modern, air-conditioned studios and sound stages at the North Avenue address, but also offered 100 acres of his Westchester estate for private location shooting.
Jack and his mother Ethel sold off much of their estate for housing development in the 1950s. Ethel Ward donated to New Rochelle the land for the elementary school which bears her husband's name. She also sold, at a reduced price, the property for Albert Leonard Junior High School. The remaining 62 acres of the Ward estate were purchased by the City with the help of funds from a New York State bond issue, and became Ward Acres Park.
