That special day everyone is dressed in their best clothes. Most grown up, are wearing the norwegian national costume. There are a lot of different ones. There is one for every little community or county. That costume says where in Norway you are from.
Some places there are performances of norwegian folk dance.
They are martching in the front of the parade. Then all the school-children from first to seventh grade are following right behind. Then the rest of the crowd. Everyone are carrying the norwegian flag, and waving with it. The kids have fluits which they use.
