This is true, but given the right conditions, those of us that live in the city can definitely notice bad air quality days. I live in the East End, a stone's throw from the Allegheny, and if the wind is blowing right, there is a distinct sulfur smell in the air.

Also worth noting that, even though our air might not be great, it was SO BAD before that anything toady is going to be better by comparison.

Yes, this is definitely true.
