Well Brett Im not certain on when I attended my first race there. I can clearly remember my Mom taking me there. The shop was small and dark and old. the building was right on the road not back like it is now. My mom could have taken me there just to look at bikes, but thats kinda far as we lived an hour plus away.
So if it was open in 79 Im not sure what sanction it was. I can remember it and my pic in the paper was taken coming out of turn 1. I just cant remember what years and what sanction. It had to NBL. but then again lol.
