Foodies have always known that locally-grown, seasonal ingredients are fresher, tastier, and more nutritious. But facing an economic crisis and climate change, the movement appears increasingly practical: it reduces carbon footprints, supports regional economies and family farms, and contributes to a healthy local ecosystem. This weekend-long expo features symposia on the locavore movement (fun fact: it was the 2007 Oxford American Dictionary's Word of the Year), workshops on urban agriculture, seasonal mixology, and organic eating on a budget. Don't miss Friday's screening of the feature documentary King Corn and a "Localicious Party" featuring yummy local chow.
