Most people in California don't realize that the air quality in the San Francisco Bay Area is actually worse than in Pittsburgh [1].

Moreover, after growing up in Pittsburgh and living in Seattle, I can tell you that Seattle definitely has less sunlight (it's not even close) than Pittsburgh. So much less that my doctor had to prescribe my Vitamin D to address a deficiency I had when I moved there (after living in Pittsburgh my whole life, no problems).
