This is a public health issue, especially near public schools. According to the Spare The Air website, violators should be reported. "You may also call 1-877-4NO-BURN (1-877-466-2876) to check the Winter Spare the Air Alert status and to report wood smoke complaints."

Please, for the sake of those with asthma (especially children,) cease wood burning. Even those up on Skyline - it all flows down hill...

...and yet, gardeners city-wide can run their 2-stroke leafblowers with tacit permission from the city.

We now have quite a few large tour buses traveling through our neighborhood and "Professorville". Some are older charter buses which appear to have been painted over all white or black, with tinted windows. I was in back of one of them on Sunday afternoon, and it was belching out dirty fumes (diesel?), while stopped at the light on Waverly and Embarcadero. These buses also park in our neighborhoods and idle for long periods of time while tourists(?) walk around.

Aside from me parking my car and getting out and talking to the driver, what can I do?
I thought diesel buses had to be retro-fitted with some kind of filter nowadays?
These buses often drive around both Stanford and Foothill campuses too.
I guess this is never going to end.
