Howard's Adventure was a former slave plantation located in Gambrills, Maryland in Anne Arundel County. The historic estate was the homestead for the prominent Hammond family of the region. The property was later purchased by the United States Naval Academy, who would operate a dairy on the site for over eighty years. The dairy farm is home to USNA mascot Bill the Goat, who would be stolen from the farm many times over the Academy's history. Today, the manor house remnants and Hammond Graveyard are found within the U.S. Naval Academy farm complex.
