Proper Display of the Flag:
* Display of the American flag is usually from sunrise to sunset.
* The flag should be displayed daily on or near the main building of every public place and during school days in or near every schoolhouse.
* Flags are flown at half-staff to show grief for lives lost. When the flag is flown at half-staff, it should be pulled to the top for a moment, and then lowered to the half-staff position. The flag should then be raised to the top before it is lowered for the day.
* When two or more flags are flown from the same pole, the American flag must be on top.
* When displayed with another flag against a wall, the U.S. flag should be on its own right (left to a person facing the wall).
