Looked like this? The dome in the middle-left is California's State Capitol building. Photo I

Our politicians didn't dream up smog rules simply to control people. Rather, they were slow to respond to the public's demand for breathable air. Then other places with air like this adopted the standards that tamed this.
And this photo isn't even local pollution. Rather, it blows in from the San Francisco Bay area where the air is always cool and fresh then is trapped up against the Sierra Nevada range. Bay Area people wondered why Central Valley cities were so insistent about air quality ... they didn't see any problem!
Actually Los Angeles was worse. Days when kids were kept indoors for recess. I was down there for business a few times per year. Getting off the airplane in Burbank was same as when you scrub a shower using too much bleach, it burned the lungs. I couldn't imagine living there. No wonder the residents were pressuring the politicians to "Do Something!!!"
So now there are air pollution standards.
