Labor and the Locavore focuses on one of the most vibrant local food economies in the country, the Hudson Valley that supplies New York restaurants and farmers markets. Based on more than a decade's in-depth interviews with workers, farmers, and others, Gray clearly documents how the romance of small family farms serves to mask the predicament of their migrant workforce. She also explores the historical roots of farmworkers' substandard conditions and examines the region's shift from black to Latino workers.--Publisher description.
