. GREETINGS !!! Does anyone know the "history" behind the Memorial Day half-staffing procedure. In other words, WHY is the U.S. Flag at half-staff until NOON and then raised to FULL staff on Memorial Day? I've got a TV News crew coming over to my house for an interview at 1:00 PM, and I can't for the life of me remember WHY it's in the Flag Code that way!!! THANK YOU !!!
