Low-carbon travel

I recently found out about an experiment one of my friends is conducting together with her fiance. World In Slow Motion is the "travelogue" for Tom and Lara's journey around the world without flying. While a pretty radical, and cetainly not a no-carbon alternative to air travel, they are definitely proving a point about slow travel, appreciating regionality and reducing their carbon footprint. Pretty amazing. You should check it out. Later.
