 But we've done a tremendous job in reducing pollution, and our air is cleaner now. I can remember days when I was a child, we were driving past the Gary Steele Mills in northwest Indiana, and a film covered our windshield as we were driving on the expressway. We had to pull off and wipe the film out. It was in the air. Or going from the Mojave Desert toward Los Angeles and watching the smog roll toward us.
