In fact the first activity on the floor of the new Rockdale High School gym is installation of the floor itself. That milestone is under way in the extremely busy renovationexpansion project which promises to have the mostly-new campus ready to open in about two months. The first day of classes is Aug. 24 but volleyball practice will get under way on Monday, Aug, 3. The existing RHS gym is being kept as a practice gym. The 12,561-square-foot new gym is part of an 18,867-square-foot wing which also includes the first new RHS dressing rooms in 50 years. Athletic lockers have arrived and are being installed in the dressing rooms.
