Perhaps it is to honor one of your state’s fallen service men or women.
In our state of Michigan, whenever a person from our state is killed in combat, the flag is lowered to half staff. The Governor orders the flag moved. It is on our state’s website listed as “Half-Staff Flag Alerts.” It is law put into effect in our state in 2006. Given the number of wars/conflicts/battles going on maybe it’s not so unusual for the flags to seem to be lowered so often.
Yes, there are vets in this particular cemetary. I just assume this is why the flag is at half staff 24/7 360 days a year.
Who knows? I’ve even asked our council and they all look dumbfounded!
