Hershey, PA — The Hershey Co. and Milton Hershey School are inviting visitors to thehersheylegacy.com to post stories about volunteerism and send e-cards to friends who have helped out in their communities.

Each time a volunteer shares a story, an image of Hershey’s Milk Chocolate bar will be added to the person’s city and state on a U.S. map.

The company says its site will also ask visitors how many people benefit from their volunteerism, serving as a reminder of how one person can make a difference.
