The Gen. James Longstreet Chapter 46 of the United Daughters of the Confederacy will be laying wreaths Saturday at Alta Vista Cemetery as part of the 20th anniversary of the national Wreaths Across America campaign. The effort aims to honor veterans by laying wreaths at their graves. “I think it is just important to keep the spirit and remembrance of our veterans alive, so that they are not forgotten,” said Gail Mangum, who is leading the local effort.
