On The Green Road is Cece Reinhardt and Brenda Daugherty. I came across their website when I was researching The COMET project, and since I've found them they have been infinitely helpful and supportive of me. They were my first official sponsor! They really are wonderful people and what they have done and are doing to educate people about sustainable, mobile living is amazing.
Cece and Brenda travel the country in their gorgeous Airstream, which has been completely retrofitted with sustainable, green building materials and technologies in alternative energy. They tow their classic Airstream with a truck that runs on Biofuel (waste veggie oil). These visionary ladies give open houses and informational sessions in their off-grid Airstream, spreading the word about sustainable, healthy living. The two of them live in their Airstream full time, they even have a cat!
