On Mike Pink's potato farm at dawn, the sun is an angry red ball low in the sky.
This summer, wildfire smoke has blanketed much of the West for days and weeks. And that smoke has come between the sun and ripening crops.
Pink watches as his year's work tumbles onto a fast-moving belt and into a waiting semi truck. He's got most of his 1,600-acre potato fields yet to harvest on his 3,000-acre farm, spread over about 40 miles between Burbank and Basin City, Wash. And this thick smoke makes him nervous.
