Minnesota Malaria
Malaria: not the disease, but the literal meaning of "bad air".
For the past few days, the twin cities have been under a nasty temperature inversion with no wind, with the result that we've had gawd-awful air quality (by Minnesota standards, at least - this is probably a normal day in Houston). It's finally getting better, but we peaked out at an AQI of 154 or so - unhealthy for all concerned. Outdoors activities are to be limited, especially by the young and old. Right now, it's more like 95, which isn't great, but it's tolerable and improving.
The girls were coughing on monday and tuesday, my eyes hurt, and Molly and I both had headaches on wednesday.
Makes you appreciate living someplace that has good air quality, at least most of the time.
