 Weadick invited ranchers to enter their wagons and crews to compete for a total of $275 in prize money.Officially called the Rangeland Derby, and nicknamed the "half-mile of hell" or the "dash for cash", chuckwagon racing proved immediately popular and quickly became the event's largest attraction.While only six teams raced in 1923, today's Rangeland Derby consists of 36 teams competing for $1.15 million in prize money.
