Well it is airborne in Illinois. We have not had rain for about three weeks which is great for farmers at harvest time. They save drying costs on their beans and corn, but the combines stir up dust as they harvest which becomes this airborne cloud of dirt, fiber from the crop, and plant material which simple gets so thick it is like a forest fire. My wife's allergies are off the chart as she has draining sinus infection which will not get better until we get a drenching rain to know this crap out of the air, but all that poison is airborne and people are breathing it in......cancer is a complex disease, but we certainly should try to minimize the impact of chemicals on our citizens.
