That isn&amp;#039;t enough to keep the stands from filling as the start time approaches. An annual Indy 500 event is a lap by some of the vintage Indy cars and this year we had an historical moment.  1978 Formula 1 champion Mario Andretti was driving a 1921 Duesenberg, the winning car in the 1921 French Grand Prix driven by Jimmy Murphy. It was one of two American cars to ever win a Grand Prix race. The other U.S. winning car is, of course, the Eagle driven by Dan Gurney to win the 1967 Belgian Grand Prix. We then got a group photo of the Indy champions who were honored. From left to right, Rick Mears, Tom Sneva, Arie Luyendyk, Bobby Unser, Buddy Lazier, Parnelli Jones, Johnny Rutherford, Gordon Johncock, Mario Andretti, A.J. Foyt and Kenny Brack.
