Over the past couple of years, the concept of eating locally has taken hold of the public imagination. Thanks to years of on the ground work by a group of dedicated non-profits, activists, farmers, small businesses, and eaters, the benefits of eating food grown as close to home as possible has at least made it to the edge of mainstream society.
