As we drove along in the rental car in Sunshine State, I kept saying how nice it was to have the windows open, to feel the warm breeze. Then we passed through a flat section of farm, where trucks were spraying the fields with liquid. I’m not sure what was in the spray: fertilizer, perhaps, or insectides, or both. I have no way of knowing what toxins it might contain. But I rolled up the window quickly as the truck moved towards us, and our whole car was soon covered with a sticky film. When we drove back through that evening, the trucks were still out spraying, and our car was doused yet again.
