I flew this afternoon from Sacramento to San Diego, the scene of terrible
wildfires recently. The shot on the left is taking off from Sacramento,
and the shot on the right is approaching our landing in San Diego. Not quite
the same height, but you can see for yourself the difference in air quality.
The area of San Diego in this photograph was NOT part of the burn area, but you can
literally see the air that hovers over even the most unscathed neighborhoods.
