I found this cool Sunoco ad in the program for the Mac’s Continental program from Mosport in September 1970. I think this pic of”Captain Nice” pretty much sums up the reputation Mark Donohue had. A family guy who also happened to be one of the best racers who ever lived.

The Mac’s Continental weekend featured Formula A, B & C. Formula A was for Formula 1 style cars with 5.0 liter V8 engines which grew into what most of us know as Formula 5000. The starting grid included names like David Hobbs, Dick Smothers (of Smothers Brothers fame), George Follmer and of course Captain Nice himself. Also of note are some of Canada’s most important drivers, Bill Brack, Horst Kroll, John Cannon and Ludwig Heimrath. Some American readers may remember his son, Ludwig Heirath Jr. who made a few failed attempts at the Indy 500 back in the Eighties.
