Re: I had made my first visit to the Coliseum about a month before the Super Bowl, on December 16, 1966, to watch the El Rancho High School Dons of Pico Rivera defeat the Anaheim High School Colonists to win the California Interscholastic Federation championship. El Rancho, arguably the best team in the nation that year, was a rival of my alma mater Whittier High School, but my mother taught English at El Rancho, so we went to the game and rooted for the Dons.

Sorry, but according to High School Football National Championship

In 1967 the High School National Football Champion was a tie:
Reagan Austin (TX) 14-0
& Coral Gables Coral Gables (FL) 13-0
BTW the next year... they tied again. However, in 1970, Austin Reagan won it all by themselves.
