Not sure what they’re definition of recent is but I suspect the section just means where the new
interments are.
My dad is buried in the veterans cemetery in my county and every time I go out there, there is a new section filling up, so it just happened to be section 60 at this time.
So, it’s all about section 60 being the most recent.
But, why only the most recent? Why not all sections, since they contain the remains of military members who still have family members who still visit?
