Norway.
For our national day we don't have a military parades or any traditional show of force, no, we force our children to dress up in patriotic clothing and march in line in front of the royal family or other local commune leaders. The months before the day every year there are youth squads in red clothing riding in big busses rampaging the whole country.
i was very surprised last monday at the flag waving flag coloured clothes over the topness of the surprisingly large amount of norwegians at my university
