The general region is desert, water and food is scarce, but through this agricultural zone there's this dense pocket of food and water on the surface.
I was in a Miata with the top down, and the amount of chemicals they were using to keep the pests/insects away from this lush green oasis in a land of nothing was noxious. I hadn't exited my car, just drove through these fields on the farm roads, and it left me feeling sick with a headache and nausea well into the next day.
Of course I didn't encounter a single insect, spotless windshield.
