Did you know that Memorial Day—the somber holiday coming up on Monday, May 27—was once known as Decoration Day? First marked by Union soldiers in 1868 to memorialize the Civil War dead, the holiday was official recognized in 1971 and today is applied to all military fallen. In the Treasure Valley, that salute to the troops will take several forms, including two Memorial Day ceremonies—one at the Idaho State Veterans Cemetery in Boise and another at Kohlerlawn Cemetery in Nampa—and a Memorial Day Flyover at Nampa's Warhawk Air Museum. All three events start at 10 a.m., and are free with the exception of the flyover, which costs a $5 museum admission. The Boise ceremony will feature a wreath presentation, its own aircraft flyover and several speakers.
