Judging by the, um, well-used look of the shirts, I’m thinking they’ve become everyday work uniforms. My guess is that they don’t often supply shirts with the Steel City name on them, so they became a work uniform by default.

I’m curious as to whether they knew that AC’s board was in town, or if this was just the end of a laundry cycle for them.

From what I understand, they’re going to be keeping the roof (technically the “North Terrace”) open that night so people can go up there to see the fireworks. I believe there’s a staircase just on the right as you start to cross the Skybridge over Halls A and B fro the Spirit of Pittsburgh Ballroom. That will take you up to the top level, between the hyooge scrolling blue text thingies. Keep walking forward and you’re out on the North Terrace!
