Elvis entered the building at North Cobb High School in Kennesaw on Friday. Then he showed off his moves on the dance floor. Devon Ragin, 7, isn't really the King, but he may have felt like one at a dance for elementary students with special needs. About 100 students from seven elementary schools followed the red carpet into the high school gym for a morning filled with music and fun. Nearby Northstar Church and Acworth's parks and recreation department also helped with the dance.
