Veterans and other people all across America are answering a special Memorial Day request this year. At precisely 3 p.m. local time, wherever they are, they will all be playing “Taps.” One third-generation veteran will be strumming his guitar, while another man took trumpet lessons for seven months to be able to participate. The powerful tribute was dreamed up by CBS News correspondent Steve Hartman, who says, “The amazing thing about ‘Taps’ is it means different things to different people.”
