Watching Troopers perform last night in that air reminded me of what we went through here two years ago in Glenwood Springs, CO. We had two very bad fires in the area, Pine Creek just east of Grand Junction and then later, the Grizzly Creek fire in Glenwood Canyon. Our air quality was bad all summer but especially in August. I have Asthma and had to get breathing treatments 3 times that summer. Hopefully, things improve soon in the Midwest, I can't imagine performing in those conditions.
