Happy Memorial Day! Try to remember that this holiday commemorates U.S. men and women who have died—and are dying—while serving our country. The mammoth Green-Wood Cemetery offers a tribute to the more than 3,000 Civil War veterans buried there. There will be a fife(!)-and-drum corps from the 119th New York Infantry, Civil War re-enactors (uh-oh), an artillery battery, songs and wreath laying.
