I would say yes. It may be minimal but I believe if this could be imitated in a controlled test with a check there would be a small difference. Boy when the wind picked up and switched to the nw it got hazey fast here today. Has a burnt smell to it too. I was born in1980 so someone else might be able to chime in didn't the mt St. Helens event affect crops that year?
