Today is Memorial Day, and the holiday means some businesses and government offices could be closed. Before you head to the Post Office or drop your kid off at school, check our list below of what's open and what's closed today.

Woburn residents should also be aware while driving this morning that a parade and other Memorial Day festivities are going on. The parade will begin at 8:45 a.m. at the Common and move toward Woodbrook Cemetery. Stops will be made at the Jewish Cemetery, K of C flag pole, and Cross at Calvary.
