How are your lungs?

We've been having fun watching this site to keep updated on air quality around the US. Sadly, our little city has made the Top 5 for worst air quality on numerous occasions the past few weeks. That dirty air is due to inversions we often get in the winter time. Whenever that gunk starts to settle in the air, we hope for a winter storm to come and blow it away. Of course, that usually means we trade dirty air for snowfall. How does your city rank?
