The first BMX proto sanctioning body was the Bicycle United Motocross Society (BUMS) founded by Scot Breithaupt in Long Beach, California on November 14, 1970, when he was fourteen years old. On that day he put on his first ad hoc BMX race. At first BUMS simply referred to the transients that congregated in the field around 7th and Bellflower Streets where the track was located, but later Scot turned it into the acronym BUMS. The first race had 35 participants, who paid Scot a quarter (US25 cents) each for the privilege. At the next race 150 kids showed up.
