Looks like I missed that memo.
As I understand it the smog is constant in SLC-Valley until a storm moves it out due to no north or south winds.
So really....the terrible looking smog I have seen is really just SLC at its worst and the majority of the time this smog does not exist (or is not as visible)?
I spoke with realtors in Sandy and they all said if I am concerned about air quality to try and look for a house as close to the wasatch front as I can so I can be "out of the bowl"
