I hear about this and it makes me anxious. Years past a fire from a rural trash burn came across our pasture. Relatively small as it was and young and strong as l was the smoke robbed me of breath. I was shocked at how leaden my feet became and how weak my arms were as l flailed at the flames with a wet gunny sack.
I have a fear of what wind and a spark can do. People have posted good advice already, it seems.
Stay as well as you can and far away from the smoke, Coco.
