I just love it whenever I have been where the air is clear and plentiful. I have fond memories of hiking in the forests and near the ocean in the state of Washington where I grew up during my high school and college years.
Now I live in Orange County, California. I really miss the better air from up north. I appreciate it when we visit my son and his family in San Francisco. I feel better there. I think it is because the air is better than here.
