Facebook founder Mark Zuckerberg stopped by Ford Motor Co.'s Rouge Complex in Dearborn, Mich., last week as part of his "Personal Year of Travel Challenge."
The social media tycoon is touring the country to interact with people and discover how they live, work and think about the future.
The 32-year-old billionaire worked on the line at Ford's Dearborn truck plant, helping assemble an F-150 pickup truck and was shown how the company designs vehicles at its product development center.
Zuckerberg also rode in the Ford Fusion Hybrid autonomous research vehicle.
And of course, the social media pioneer posted a message to his Facebook profile.
