BILLINGS - This month is Child Abuse Prevention month, and organizations nationwide are holding events to raise awareness. A local event took place Thursday afternoon on the Yellowstone County Courthouse lawn. The crowd planted 375 blue and silver pinwheels in the shape of a ribbon on the lawn in the Family Tree Center's 13th annual 'Display of Pinwheels for Prevention'. Stacy Dreessen, Executive Director for the Family Tree, says the pinwheels represent the 37 thousand children in our community. Dreessen says the pinwheels help to express the community's commitment to prevent child abuse and neglect. Representative Larry Brewster was the keynote speaker for the event and became emotional when speaking on a personal experience dealing with the aftermath of child abuse and neglect.
