Thursday was no exception. A new B.M.C. Durfee High School is under construction. Ground was broken in late August. Trees were felled, fences were erected, and granite boulders were pounded into pebbles. So at the official groundbreaking for the project, officials lined up at a long box filled with sand to wield shiny shovels, decorated with bows of Durfee red, to throw the sand into the air, more or less in the direction of the cameras. That got accomplished. There is more work to do.
