Ohio seems to have a bit of a thing with flags. It’s not just that our state flag is the only one out of the 50 that is not a rectangle (an interesting story in its own right).
You might have seen a service flag: a blue star (or stars) on a field of white, surrounded by a red border — hanging in the picture window of a seemingly random home in the neighborhood or in a shop window of a downtown building. But many folks might be unaware, or at least unsure, of its significance.
