The great Los Angeles-to-Phoenix off-road race (more commonly known as "The Cactus Derby") was another of the terrific classics from the sport's early days. In its 1914 edition, track racing legend and barnstormer Barney Oldfield entered the same Stutz racer he had piloted to fifth place in that year's Indianapolis 500.
Of all things, a passenger balloon race. The national championship, no less. The reality is, almost without exception "fans" of the the Indianapolis Motor Speedway are all about the Indianapolis 500. There have been times in recent decades when people with little interest in the classic "500" came to the Speedway to witness their preferred branch of motorsport, either NASCAR or Formula One.
