  1. I lived in Oregon years ago, when I came back to LA and stepped off the plane onto the tarmac, I almost couldn’t breathe. The air was so thick. And that was over 20 years ago.

    1. The air in LA is WAY better today than it was 20 years ago, according to friends I know who grew up there. That is pretty scary.
