Both my mother and father are buried at Fort Logan cemetery, and last Veterans' Day I put flags on their graves.   There was plenty of staff around and no one said anything to me.

I suspect it might be the SIZE/number of flags placed that might have been the issue.

Either way, it's stupid to forbid putting flags on your veteran parents grave(s) on Veterans' Day.
Tell the staff they'd be better off doing something about the tons of goose droppings.
