There is a little burn on my right lung from my short bike ride into work today. But according to Twitter and to the Idaho Department of Environmental Quality, it's only a Yellow Alert day. The Air Quality Index in the Treasure Valley and in Boise is 93. An AQI of 100 puts us up into the orange.
But I'm gonna say, when you wake up sweating and think it looks cloudy and tear up when you hit State Street, it might as well be a Red Day. As they say on the Twitter: Today is a good day to leave the lawn mower in the garage.
