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.
Another great YouTube find - you can watch the entire Indianapolis 500 movie, "The Big Wheel" free of charge and with only one commercial on the front end. You can also watch it below from this embedded link from Internet Movie Database.
