Larger agriculture, not seen here to my knowledge, uses aircraft to spray and that can indeed drift. Not much in the way of Big Ag here. It is a big issue in California where housing developments are adjacent to hundreds or thousands of acres of field crops.
Rob, I agree with all of this. However, I'm thinking that the problem is actually worse during calm winds. Higher winds will dilute the vapors and carry them away, whereas calm winds will allow the vapors to linger around the area for a much longer time. I don't have a link to support, I only have my own experience with applying solvent based finishes. On a windy day my carport is well ventilated, on a calm day I need to set up fans or the smell gets very thick and it lingers in the surrounding area.
