I don't go to games often, due to living in AZ, but a few years ago we went to a night game against the Astros (Johnny Estrada hit a grand slam and Damian Miller hit a walk-off Jack, as called by Jim Powell, the next afternoon, in case you're trying to date this. Anyway . . . ) and we sat in the terrace box seats that are on our season ticket plan. With the roof closed and no air circulation, it was completely terrible to sit through--worse than sitting in the cold at Lambeau or a rain delay at County Stadium. I had to leave my seat several times because, with exercise-induced asthma, I just couldn't breathe. I had to get out of there. It's probably the closest I've ever felt to "dying." Like others have said, some fans or something. Or, um, how about install some actual air conditioning throughout the ballpark? It's not like you'll use it as much as the folks in Houston or Phoenix do but it'd be nice on those brutally warm and humid (that's the main thing, really, is the humidity) days and nights. Heck, maybe they could put install some windows on the 1st base and or 3rd base side walls of windows above the upper deck that open up and create some air flow. Or would that create a huge draft that would blow balls out to the bleachers even more? I'm no physicist so I don't know.
