Summer of 1969

A lot of people went to Woodstock in the summer of 1969, but I went to the races with my Petrie FT SLR and it's 200mm telephoto lens. The first race was the SCCA Formula Continental Championship Series at Seattle International Raceway near Kent, WA. There were several classes of cars, and Formula 5000 had the biggest engines, 5 liter V-8 from Chevy, Ford and others. Number 77 here has a Chevy engine which shares parts with the Trans AM cars and was driven by Fred Corbett. This race was won by former RAF pilot John Cannon in number 2, one of Dan Gurney's Eagles with a Chevy engine.
I remember very impressive fast lap times (compared to the local sports cars driven by weekend warriors), in these light powerful cars with high wings mounted over the rear of the car. Only the latest from McLaren, Lotus and Lola had wings on the front of the car, and they weren't faster, possibly because those wings created more drag than downforce? Here's a shot of what looks like a McLaren in the pits being admired.
Little know fact - we have a corkscrew on the backstraight, coming off of turn one, down a hill, with a tight right handed, then left handed turn on to the straight. During the race, we would watch them enter turn one, then run over to the esses (as we called it) where the cars were slower and we could see them longer.
