When I first started going to LA in the 70s, the air was like that nearly every day, and usually much worse. It took a lot of work and cooperation between CARB and EPA to make the tremendous progress since then. Still could be better, of course. Younger people have no idea how bad things used to be there and in most other U.S. cities.
