We've all heard the expression "a house divided," but what about a yard divided? For the Harders, that was a major challenge. One of the selling points of their Savannah, Georgia, home was its spacious parklike yard -- but the only way into their large backyard was though a rickety gate at the back of a high privacy fence or through the side door of their garage. As a result, they rarely used the backyard except as a space to grow vegetables. But the Grounds for Improvement team is about to bring some unity to the space and, in the process, add some interesting focal points.
