Update:
Well, the air cleared for the last two weeks. I left Monday and got home yesterday afternoon, just in time for the latest Air Quality Alert for today/tomorrow.
Good to hear you made a window with OK air quality. I am watching the current plume with interest. I came through Madison yesterday with intention of heading to St Paul. Depending on the readings tomorrow to see whether I take an air quality rest day, ride with a N95 or ride normally...
