There's only been 1 time that I have been to Miller Park and been truly uncomfortable--almost couldn't breath uncomfortable--and that was an evening game with high humidity and temps in the high 80s. It was a night game against Houston, Johnny Estrada hit a grand slam, and the Crew won. But I just about passed out once they closed the roof and the air in the terrace boxes (and the rest of the upper tank, I imagine) just got heavy and still. When the roof was open, the air moved around and it wasn't bad. But with it closed, it became stagnant and those people, like me, with breathing problems already were not comfortable. I know I began to hyperventilate, just trying to get enough oxygen in my system. At that time, 10 plus years of living in the dry desert was what did it to me. My lungs just weren't used to that high level of humidity without any air movement. I guess, if A/C was not an option (I like the idea of putting it in the terrace concourse, at least), they really need to get some fans installed or something, just to get the air movement. I'm probably in the major minority on this one, though. I don't get to many games in Milwaukee anymore (< 1 game per year) so I guess whatever they decide is the best.
