Henry Packer Deering was Sag Harbor's first United States Custom Master at a time when Sag Harbor was a more active port than New York City. His home/workplace, was relocated to its current location, and is now a museum. The cache is on the grounds of this historic building.
By 1789 Sag Harbor had more tons of square-rigged vessels engaged in commerce than even New York City. On July 31 of that year Sag Harbor was declared the first official port on entering United States territory. This is where ships would stop before sailing to New York City to finish their trip. With all the ships coming in and out of Sag Harbor the United States government decided that they should place a customs house in the town. Access to the cache is mostly level ground, and no bushwhacking is required to find it. Find Deering's home and explore the grounds.
This was one of six caches placed as part of the John Jermain Memorial Library's Sag Harbor Culture and History Geocache Hunt. Each cache was located near a site of cultural or historic significance to Sag Harbor. The Library's geocaching hunt has ended, and four for of the caches were archived. This one, and TiffanyX2 remain available to find.
