In the late 1970s (this picture is from 1979) we used to have a night race at Bonneville Raceways on the West side of the Salt Lake valley. This was, to us, like racing supercross at night, in front of a crowd, in what was basically a stadium with bleachers, concessions and paved pits. No wonder this was a popular place.
The track was relatively simple with limited space on the infield of the stock car oval to work with. There were lights, of course, and turns, jumps, whoops and some short straights to whip it up to speed before braking for the next turn as shown. I am squeezing the front drum brake on my 1979 RM125 with a 4-finger grip, such was the pre-disc brake braking performance of the time.
