Minneapolis is about 190nm south of the fires going on in the BWCA - with help of the Canadian fires just North of Ely. Smoke had visibility at our local (KFCM) airfield at 1 mile this morning from the smoke. IFR. I got to wonder if this is going to impact the Oshkosh airshow next week... as what we would travel up is not up for that type of visibility.
