Tennis polo
The sport is played on a grass field between 80 and 100 yards long and 50 to 65 yards wide. The goal area is a semicircular line with an 11-yard radius and the penalty mark at 13 yards from the goal. An experimental rule has a second semicircular line on the field with a 17-yard radius. Generally, a field for gridiron football or soccer can be used.
World Series of Football (1902–03)
Madison Square Garden had to be redone to accommodate the teams. The wooden flooring of the arena was removed and replaced by an earthen surface. During the event the goal lines were only 70 yards apart and the playing field was only 35 yards wide. The earthen surface also became sticky as the game progressed and made for some tough maneuvering, while the stands were right up to the playing field and proved to be a physical hazard. The kicking game was also drastically affected. In a game on a normal field the team with the longest punts had the advantage. However, the Gardens proved to be a dream for a weak punter due to the field size. The arena wall was right on the edge of the field, presenting a serious hazard for any sideline plays. One player reportedly knocked himself out of the tournament by running into the wall on the opening kickoff.
