Two ordinary city slickers quit the "real" world and go wandering around the globe. The trip started in 2009 with 16 months cycling in Africa, covering 12,000km through 12 countries. After an intense eye-opening experience, we have given up the bikes and are heading from New York down to Rio de Janeiro by bus, hoping to arrive in time for the Rio +20 Earth Summit in June 2012 and filming grassroots environmental organizations along the way.
