1972 was my final year traveling to Watkins Glen for the 6-Hours and Can-Am races.   Major changes from previous years.  In the endurance race, the Groupe 5 Porsche 917s and Ferrari 512s are gone.  The races are now won by the open-top, 3-liter, Group 6 racers.  The main combatants are Ferrari and the Ford-Cosworth powered Gulf Mirage teams.

Porsche may have been gone from the 6-Hour race, but they certainly came to play in the Can-Am.  Team McLaren (Denny Hulme) and Penske Porsche (George Follmer) each had one win coming to the Glen, but the guard was changing.  Follmer would go on to win the Can-Am title for Porsche in 1972, ending five years of McLaren domination.  In 1973, McLaren would not return to the Can-Am and Porsche would win every race.  But that is still in the future . . .
