I'm not big on sports, either, but I remember going to Pirate baseball games at Forbes Field and seeing Bill Mazeroski play. (To quote a local commercial, "It's a 'burgh thing").
The most memorable sporting event I attended, however, was not as a spectator, but as part of the half-time entertainment at a Steelers' opening game at Three Rivers Stadium. A dozen of actors were engaged as DANCERS! to perform 1950's dances on the field. We made our entrances in twelve classic cars, then as Pittsburgh legendary d.j., Porky Chedwick, spun some discs, we danced. . .My partner was my dear friend (and playwright) Coni Congoli-Koepfinger. All of us had rehearsed together for a week, rough when you're not really a dancer.
To me the fascination was being in the "back stage" areas of Three Rivers Stadium - the locker rooms, the offices - and making that exciting entrance perched on top of the back seat of a yellow convertible! Dad, who had a Steelers season subscription for as long as I can remember, was in the stands for the game and he brought along our Bell & Howell 8mm camera, so there are actually films of this particular half-time show.
