LOW TECH 1, HIGH TECH 0 For many years it housed Rockdale High School's technology department and art department. It came down in one afternoon last week, the final "piece of the puzzle" in the renovated expanded Rockdale High School. Technology and art are now inside the high school. All of RHS is now either new or has a "new look." Outside walls in the 1950's-era building have received new windows and have been incorporated into the new design. The many portable buildings in the RISD have been sold and moved off site.
