One word for ya. Inversion. I hated winters in the Treasure Valley for that alone. Other than the inversions, winter wasn't bad. Of course, I lived in Nampa, so the inversion also smelled of sugar beet processing. Which smelled worse than just about anything but rotting flesh.
Yeah. We have the inversion in Salt Lake too.
Still it’s better than living in LA, SF, Seattle, Baltimore, Philadelphia, etc etc.
