The sport was conceived shortly after Hoover's
1928 election. While on a trip to
South America, Hoover observed a game of "Bull-in-the-Ring" being played on the Battleship
Utah. Bull-in-the-Ring was popular among
navy ships and was an inspiration for Hooverball. In Bull-in-the-Ring the ball was soft and weighed 9 lb (4 kg). The person in the middle of the circle was called the "bull". While on these navy ships, Hoover enjoyed watching and playing the game. The net was 8.5 to 9 ft (2.6 to 2.7 m) high and 30 ft (9.1 m) wide. The New York Times described it as a "distinctly strenuous affair, best understood as exactly like tennis except that the net is eight feet high, there are no racquets and the ball is a hefty medicine ball weighing from 5 to 9 pounds. ==Rules==
