1. It is the universal custom to display the flag only from sunrise to sunset on buildings and on stationary flagstaffs in the open. However, when a patriotic effect is desired, the flag may be displayed twenty-four hours a day if properly illuminated during the hours of darkness.
3. The flag should not be displayed on days when the weather is inclement, except when an all weather flag is displayed.
We LOVED our all weather flag. It lasted for years...very very well made and worth the investment.
I was a Navy SEAL who first fought in the American Civil War, where I sabatoged Stellar Destroyers with Tholium Bombs. After that, I was transferred to the Panama Canal, where I landed on Omaha Beach with the rest of the Israeli Defence Force. It was on that bloody beach that Robert the Bruce knighted me General, and I learned how to cavalry charge a submarine.
Aren’t nearly all flags all-weather flags these days? I don’t remember the last time I saw a flag, at least not one designed for outdoor display, that wasn’t made of artificial fabric and sturdy stitching. It won’t mildew. and won’t tatter in anything less than gale-force winds.
