Local enthusiast Murray Chambers got into all these events because he took photographs for Motorsport in British Columbia magazine publisher Doug Harder. Harder also produced the demolition derbies that began in Callister Park across the street from the PNE in the Sixties and later through the Seventies and Eighties on the fairgrounds during the annual PNE Fair. In 1970, he brought Hollywood film stunt driver Ron Walker to Vancouver to deliver a thrill show on wheels. “I needed to give the demolition drivers an hour or so to repair their cars after the heat races and get them running again for the main event which wrapped up the show. So, I got the idea to have a stunt driving segment,” he recalls.
