With names like “Fork in the Road”, “Viva La Waffle” and “Truckin’ Good Food”, colorful food trucks have proliferated across American cities over the last decade. Thanks in part to the explosion of social media, which is rapidly changing the way we buy, cook, and learn about food. Baylen Linnekin is the founder and executive director of the advocacy group ‘Keep Food Legal.' He also created and taught the class “Foodways 2.0: Social Media, Food Trucks and Underground Food”, at American University. AU first offered the course last fall.
