Went to that game as well, my father mailed me the tickets, he was a season ticket holder and lived in Pittsburgh. I had moved out to California in 79. I remember the Steeler side was the west side of the Rose Bowl, Rams were on the opposite side. When you walked into the stadium they were handing out these mementos that were silver reflective material I believe. The fans on the east side were using them to reflect the sun as it set behind us and were trying to blind us at the games beginning.
Anyway scalpers were selling tickets before the game between 30 and 40 dollars lol.
