Have your kids ever wondered what it feels like to wear an Olympic gold medal? They will have the opportunity to find out Sunday at the grand opening of the Dominique Dawes Gymnastics & Ninja Academy in Rockville. It’s the second location for the gym operated by gold-medal-winning Olympic gymnast Dominique Dawes, 46. She’ll be signing autographs, the gold medal will be available for children to try on and take photos with.
