THE COMMUTE: A lot of us commute to work five days a week. What is the healthiest way to do that? The City of Tulsa has an awesome tool to help us make that decision. It is called green traveler and is located at http://www.green-traveler.org/ . I have chosen biking because I bought a house close to work. But depending on where you live, green-traveler helps you choose between walking, biking, carpooling, and the bus.
