Curt Ellis (pictured) and Ian Cheney won rave reviews for their 2007 documentary King Corn, about the drawbacks to industrial agriculture. They built on that success by filling up the back of a 1986 Dodge Ram with soil and planting tomatoes.

Over the past few years, the two friends have driven their Truck Farm from neighborhood to neighborhood, giving urban kids a chance to get their hands dirty, and see how food looks on the (moving) ground. They produced a film on the project in 2011, Truck Farm, and they’ve enlisted such singer/songwriters as Jack Johnson and Charlie Sutton to attract the crowds.

It’s not likely we’ll be sourcing the majority of our food from moving vehicles in the near future, but the Truck Farm project shows how thinking outside the garden box can introduce a new audience to natural foods.
