Challenged Child and Friends held its 11th annual Rock in the Spring concert fundraiser Saturday evening at Brenau University amphitheater. This year’s numbers aren’t yet in, said Cindy Wilson, Challenged Child’s director of development and marketing, but the 2013 concert netted “about $40,000.” Rock in the Spring is one of four fundraisers for Challenged Child, Wilson said. The Murphy Boulevard school provides an integrated experience for children with developmental delays and disabilities learn in a full-inclusion program with children who have typical development.
