Saw a listing today over on Yahoo! News that listed the top ten most polluted U.S. cities. I don't think it's much of a surprise to anyone that Los Angeles is topping the list. Also on the list are Detroit and Pittsburgh, which to my brain, have always been somewhat associated with a grunginess factor.

Slightly suprising to me was that St. Louis was on the list. I have been to St. Louis and it seemed clean enough for my liking (except maybe for the Mississippi River). I was also slighltly surprised by how many midwest cities were on the list. I've always known the west coast had pollution issues, but I would have thought the east cost would be worse than the midwest based on population density. Perhaps the east coast is more forward thinking than us midwesterners and have already started reducing pollutants. After all, the east coast is the most mature portion of the country.
