Nicole Muller started a food collection initiative called Neighbors-4-Neighbors when she was a 16-year-old Western Albemarle High School student. Now, four years later, she's continuing her efforts at the University of Virginia and Neighbors-4-Neighbors has just hit a major milestone. Four years ago, Muller set out to raise 500 pounds of food. Now, she's raised 500,000, and her work has helped people across the country put food on the table.
