Thanks for the pictures. I would go to upstate NY from 1970 to 1979 to watch the F1 circus. The bark of the Cosworth V8's, the high pitch wail of the Matra V12, the distinct thrum of the Ferrari and Alfa flat 12's. Cars would visibly move around and drift thru the turns, as aero did not stick the cars. Lots of opposite lock on corner exit. Security was not like today, you could watch the mechanics work, sometimes all night. Actually talk to some of the drivers if you were lucky and cared to. Today it is all very different. I love to see pre 1980 pictures of motor racing. The original Can-Am series was cool also.
