This is a two-part series of articles that ran in the Saturday Evening Post in 1925. They are an autobiographical overview Oldfield wrote with the assistance of William Sturm. I judge some of this material to be inaccurate, not because Oldfield embellished (not that I put it past him), but because I think he simply forgot things.

In many ways, the riding mechanic played a role similar to spotters with headsets standing high above ovals on the roofs on control towers today.
