This just means that you should not display it so that it hangs in a puddle of water or such. If the flag can't get wet, are you supposed to bring it in every time it rains ?????
How stupid !
And you don’t want to ever wash your flag either, since it would have to touch water.
Dry clean only!
“If the flag can’t get wet, are you supposed to bring it in every time it rains ?????”
Yes.
(c) Inclement weather
The flag should not be displayed on days when the weather is inclement, except when an all weather flag is displayed.
