Today is the observance of Memorial Day here in the U.S.A. It is the more somber of the two patriotic holidays celebrated on a wide scale. The other, of course, being Independence Day.
Memorial Day, or Decoration Day, was started to remember those who died in service to their country, which at the time meant as a participant in a war. It has been expanded beyond military service to include various forms of civic service, and, I think, many people use it as a time to remember any who have gone before us.
I grew up in a very small town. Memorial Day was always a big deal. My grandparents and parents belonged to the American Legion Post in our town (one of two active social organizations). I spent a lot of time selling paper poppies (in remembrance of Flanders Field) in middle and high schools.
The big event was the town parade and memorial service. The parade was fairly short, in both distance and length. The marchers completed an eight block circuit. The participants were the Legionnaires, any active duty service members home for the weekend, boy scouts, girl scouts, high school marching band, and volunteer firefighters.
The first time I took my now-spouse home to meet my parents was over Memorial Day weekend. I think he was both bemused and touched by our small town celebration.
After the parade, those gathered would move from the center of town to the cemetery on the outskirts of town for the memorial service. It was a simple ceremony that lasted a short time. It always ended with a trumpeter from the high school marching band who was hidden from sight playing Taps. It was eerie and moving at the same time.
My family would then proceed to my grandfather's grave in our own personal remembrance activity. Mom and grandma had usually placed an urn of geraniums, other flowers, and a flag a couple of days before. While Grandpa was a WWII vet, he didn't die during the war or from injuries sustained during the war. It was just our way of marking the day.
I don't remember ever travelling as a kid on Memorial Day, unless it was into the city to visit the graves of other relatives. We'd usually go home and have a picnic, sometimes with neighbors or cousins. While I have at times participated in the great migration, I usually think of the day as a time for reflection and picnics.
Wherever you are, I hope that you are enjoying your day, and if you so choose, think about your ancestors, particularly those who have served their country in some capacity.

P.S. While writing this, my sister called from Iraq. She's there on active duty. It's such a reassurance to be able to contact her via email and to hear her when she can call. I can't imagine what it was like for family members in the past, when they had to wait weeks or months to get news from those serving in the wars.
