Anonymous said...: Funny how some East Coast cities get consistently better air quality than "rural" Wisconsin. The sad thing is that all this pollution isn't even caused by the production of anything of value. It's just form people driving their cars 10 miles to get a jug of milk.; December 30, 2010 at 2:12 PM
