The weekend before I go to the cemetery and place flags at the graves. And the weekend after I help remove them. I started doing this as part of my son's Boy Scout troupe and have continued when he aged out.

Not sure if "celebrate" is the right verb... I chose to "remember".

Personally i remember "Freddy" Joel Ransbottom. He was MIA in 1968 and his remains were found and came home in 38 years later.

I tell his story every year.
