The layout of the circuit is very well done, but there are no mountains in the vicinity of Buenos Aires, in reality it is a great plain .. Actually from the exit of the second curve to the next to last curve (the "hairpin") is all green with buildings only in the background on the horizon (at that time it was more marked). The buildings are seen in the near horizon on the next to last curve. You can see this with the "street view" of "Google maps".I send you some slides taken by me in the 1974 GP, inl 1975, 1976 , in that order. Great job!!!
