PORT ANGELES — Reservations can be made now for a trip to Ballard this Sunday to celebrate Sytennde Mai, Norwegian Constitution Day.

The Port Angeles Sons of Norway Lodge 37 has chartered a bus bound for the community a few miles north of downtown Seattle to take participants to the largest event of its kind outside of Norway, said Gay Knutson, one of the organizers.

Last year, 25,000 people attended, she said.

The bus trip costs $30 for nonmembers of the lodge. Stops are scheduled in Port Angeles, Sequim and Jefferson County.

It is expected to arrive back in Port Angeles between 9 p.m. and 10 p.m., she said.

“Space is limited, and those interested should act quickly to avoid disappointment,” Knutson said.

Ballard’s Bergen Square will be the site of traditional dancing, singing and instrumental performances while the streets are filled with food carts and other vendors, she said.

More than 100 entries are expected in the grand parade, which will begin in the late afternoon.

Traditional costumes from throughout Norway will be worn by many of the participants.
