I learned proper flag etiquette from my kids going through Scouts or eles I wouldn't know it .. Most don't know a Flag should only fly at night if it has a light on it . Or a torn and tattered flag should be retired(burnt in ceremony).. Or the flag should never be clothing, underwear,helmets anything but the flag itself .. I just chalk it up to people don't know any better.. Only one that really Erkks me is a hotel in New Hamshire that flys the Canadian Flag higher than the USA.. Not in This Country.. Old Glory should be flying higher than any other flag in its presence..
