Flew to a pancake breakfast on Saturday here in mid-Minnesota...visibility was bad at takeoff, got really bad halfway between here and there...prolly less than 3 miles visibility at best. I stayed low, but then they threw in scattered clouds at 1000 ft AGL, so a bit of a slalom. Amazing how spotty the dense smoke is. Those wildfires have been a nuisance.
Vic Syracuse posted about an hour ago, said smoke was bad coming from Tennessee...3 miles visibility but cleared up nicely north of Chicago.
