A Global Road Trip

The World is planning an epic road trip for you this weekend with transportation and travel stories about how we get around, and the challenges that come with the human impulse to move. We talk to the man who visited every country on the planet (without flying!), look at the environmental impact of cars, even take a swim and head to outer space.

Listen to The World, weekdays at 3pm on GBH 89.7
