I've got Western Pa roots (McKeesport and Westmoreland Co). The Steel Curtain was something in those days after years of horrible teams.
My favorite story, Dec 30, 1978. My wife and I had the audacity to get married during the Steelers playoff game against Denver. The Pittsburgh contingent had timed the trip from the motel to the church, barely beating my spouse down the aisle. Then they used white shoe polish to put then final score on our car. Damn stuff never cleaned out
