Southeast Texas where I am is pine tree country - pine tree pollen is yellow. When that starts, everything is covered with yellow pollen. One has to wash the windshield of the car so one can see out before driving.
The male cedar trees are rust colored now. The dust that covers the windshields, outdoor furniture, etc., is chalky colored. When you clean the car glass, it turns the towels olive drab green. I wash my windshield about every two days.
