Intriguing article. I live in a small city, work long hours and care for my two grandchildren who live with me, rarely having the opportunity to walk. But, I love to walk and spend many hours doing so on the every three-to-four months trips my husband and I take to a small, but artsy and historical town two hours south of us and on our annual trips to Manhattan. I always feel more creative in those places, but thought the cause had more to do with environment and ambiance. Now, I see the surge of creativity may have more to do with the actual walking than the places where I walk. Intriguing and inspiring.
