That wasn't my first game, but I definitely remember that weekend and the first-ever night game. Was at the pep rally in Stepan and my old man bought one of the jerseys at the auction (also got a ball autographed by the "all-stars.") Sounds almost like you were following me that weekend.
My first game in personal attendance was green jersey game v. SC in '78 - I was five and have vague recollections of Star Wars halftime show...don't really remember the game much.
