Hundreds of farm workers and their advocates marched through Greenfield on Sunday, to make their case for better treatment for laborers. At least 1-thousand people gathered at Patriot Park, before making a 4-mile-long march through the city. The event, organized by the United Farm Workers, was designed bring attention to Senate Bill 104, The Fair Treatment for Farm Workers Act. The march was also meant to honor Ceasar Chavez, whose birthday is on March 31st.
