my first memories of Memorial Day was a Great Uncle, Grandma's Brother, he had been in France in WWI, Infantry, we'd go up town and go the annual parade, he'd tell me what we were doing there and why. "Spud" (Uncle's nickname) would always bring his flag and campaign hat. His was the first Military Funeral I attended, he's buired in the National Cemetary in Ft. Gibson, Oklahoma.
When I was in the National Guard, I was a part of the Flag and Rifle detail every year, I lived close by and Farmed, so I was available most any time. We'd usuallly make at least 2 parades each year.
