I knew Texas would be far down the list. I hate that I can't even take a really good deep breath outside. :( It seems like the colder states are just generally healthier, which makes a lot of sense. I've been to a lot of the northeastern states, and, loved the air there. And, I was in Wisconsin for a week last summer, and, loved it, too. I lived in Washington for two years, and, miss it so much! I'm actually a native South Carolinian, and, I'm not surprised by it's placement, either.
