It is interesting how uninformed people panic over what they can see but are blissfully ignorant over what they can not.
Example: Here in Atlanta, the non-natives start complaining about pollen every spring when they see the yellow pine pollen cover everything. They think that pollen is what they are allergic to.
The truth is that the pine pollen is so large that the nose hairs filter it out quite effectively. The Oak and other hardwood pollens (and gresses) are so small that they can not be seen but they are the ones that get past the nose hairs and cause the alergies.
It is so sad when someone knee jerks without thinking. The @#$%& would do better to improve an air quality that needs no improvement is they banned automobile traffic from downtown Durango instead of focusing on the minute amount of coal smoke from the D&S.
