Good News

When the wind is not blowing, and there is an air inversion it often gets tough to breath outside. Especially, when the
wind is from the Southwest, directly from O'Hara Airport. (one of the busiest air ports in the world)

I should add that the air is cleaner than it used to be 20 years ago. Cars are much cleaner now than they were.
Coal is not burned in furnaces anymore, and factory pollution is much less than before. Trucks are also better, but some
are still bad. If the wind comes off of Lake Michigan, then the air is very clean. The lake is about 6 miles east of
where I live. The airport is about 8 miles Southwest of where I live. When planes head for New York City or Europe,
they fly over where I live. And the noise is very annoying.

Also...Very Important...Air Now publishes clean air reports for all areas of the country.

Here is a link for Air Now...just put your zip code int the space, and you get the air in your location:
