I'm looking for a place to retire in a few years. I've narrowed it down to these three cities although I am open-minded to other places. I'm interested in good medical care, clean air and the simple life. I don't want to live too far away from stores and such; would not mind living on an acre or in a small downtown area. Can anyone please tell me what they know about any of these places?

Can anyone comment on air quality in the tricity area? I'm getting conflicting information and I'm trying to select a city for retirement in the near future. I've read the "bad" air can just sit there and the area is even affected by Oak Ridge in Knoxsville. Please help
