Once more prove that Starboard and Portside should be introduced to replace left and right!
When I teached (reefer technical subjects to grown ups) I used to say:
"the only stupid question is the question you are affraid to ask as you will never know the answer".
That flag is the flag of Friesland, Ray, a province in the north of my country.
I was born there, in one of the eleven towns (Harlingen at the sea side).
Like some other places in other countries Friesland has it's own language (Fries)
Fries is spoken primarly in the rural area's, less in the towns. I understand it but do not speak it very well.
And it has it's own flag:
The red hearts are leaves that float on the water.
The blue symbols the skies over Friesland.
The white symbols the reflection of white clouds in the water.
I also use the flag as avatar next to my BritBike posts.
The Frisian flag is the most beautiful flag in the world. It's older also than any other flag, and has inspired some other countries to use red white and blue also.
