Aged only 18, Ray Seymour was already an accomplished racer. During the 1909 season, he set several records at the LA Coliseum at 72 mph and 73 mph in June. Then in July he secured the world record for the mile at 76.6 mph. He went on to win more races at Playa del Rey, the LA Coliseum and other locations across America riding a Reading standard.
Reading Standard decided in 1910 to stop sponsoring racers, so Seymour moved to Indian and got his own factory tuned 8 valve. Seymour was leading the race in the New Jersey Motordrome on Sept 8, 1912, when his Indian teammate Eddie Hasha lost control and crashed. The accident killed Hasha, racer Johnny Albright, and 6 spectators. The spectators were children who were watching the race from the stands just above the upper guard rail. All but one of the dead were less than 21 years old. This was the deadliest event in board track racing history, and the public outcry from it forced the NJ Motordrome to close forever on that day. In time, the outrage from this and other accidents ultimately killed off the sport of board track racing.
Two of the injured later died in hospital bringing a total of eight spectators killed.
