Nope. Nashville has pretty clean air. The only time we get an air alert is when there is high pollen.

BUT back in my triathlon days I used to cycle to work a couple of times a week -- that's 60 km / 30 miles each way. The last `15 km was along Parramatta Road which, in rush hour, transforms into an urban varicose vein. On a bad morning the air could look just like that and it tasted just the way that looks.
