From the Dumbarton Bridge, you can easily see the Bay Area air quality with your own eyes. Just look towards the horizon in any direction. For the past couple of days, the air has been getting browner and browner. I'm surprised they took this long to issue an air quality warning.

Please folks, use common sense. Don't light up on sunny days. If you must light a fire, do it only on rainy days. Your kids health is at stake. Thank you.
