There are certain ethical requirements for the display of the Flag but they aren't iron-clad. Flags should be lighted at night and I found a solar powered flag illumination gizmo at Lowes that attaches to the pole and it looks good from where I am sitting. Flags that are deteriorated to the point that they are no longer usable should be burned rather than discarded in the dumpster. I find that to be acceptable and I have never seen a Flag discarded in twenty years of casual dumpster views.
