Harvest bans

In hot, dry windy weather, harvesting dry crops like wheat is a fire hazard. There used to be Harvest Bans. Now warnings go out, and farmers are meant to make their own risk assessment.

“It’s the dust,” says Travis. “Fine particles of grain floating about, lots of oxygen, they’re flammable.”
I imagine a tractor or one of those giant harvesters on fire, setting fire to the crop on every side. The operator would have nowhere to go. Scruff boy, for example, could be trapped. Hurt.
