I do not know the correct numbers. Has anybody thought more American drivers involved could save this problem. Anybody remember going to Milwaukee, Trenton, IMS, Phoenix, and many others. As a kid I remember my heros were Americans. And we would even rib each other on what States the drivers were from. Even mechanics like Watson, Bignotti, Beckley, Kuzma, Epply, Brawner, and so many others who had pride.Then the rear engine cars came and kicked the dirt cars out. Then the American drivers were less and less.
