AVONDALE, Ariz. -- On one side of the stage was a U.S. color guard comprised of an ROTC unit, on the other was a contingent from the local Mexican consulate flanking that nation's flag. The invocation was offered in Spanish and English, and the Mexican and United States national anthems were performed by Latin singing stars. Eventually, the sky over Phoenix International Raceway was filled with the sound of one common language -- the rumble of race car engines.
