SEABROOK — The town’s 250th anniversary celebration is coming to a close this weekend with a bang, highlighted by a themed dance and the annual Old Home Day festivities.

Residents are invited to attend the grand ball and banquet on Friday. A chicken and roast beef dinner will be served followed by an evening of dancing at the American Legion at 169 Walton Road. Cocktail hour begins at 5:30 p.m. followed by dinner at 6:30 p.m. and dancing from 7:30 to 10 p.m.

Tickets are still available at $35 per person and will be sold at the door, according to Oliver Carter, chair of the 250th anniversary planning committee. People are encouraged to dress according to the theme, which spans the period from Colonial times to World War I. Costumes are not required, however.

“We’re doing Colonial because it’s from when the town was incorporated, it was the Colonial period,” Carter said. “We’re going up to WWI because on the coin, there is a picture of Raymond E. Walton, who was the only soldier killed from Seabrook in WWI.”

In addition, 2018 marks the 100th-year anniversary of Walton’s death in 1918, Carter said. The town is selling sterling silver coins for $75 and gold-plated coins for $25 that feature Walton on one side. The flip side features the Old Man of Seabrook.

Town Manager Bill Manzi will serve as the master of ceremonies and give a brief history of Seabrook in collaboration with Eric Small, president of the Historical Society of Seabrook. The 250th anniversary festivities Wednesday night included the burying of a time capsule.

Following the banquet Friday night, the 250th birthday celebration will focus on Saturday with the town’s regularly scheduled Old Home Day at Seabrook Elementary School, 256 Walton Road.

Carter noted there will be a party for children, corn shucking, clam shucking and a contest to pick the best homemade pies. There will be several events on the stage, including the introduction of the pageant winners from Baby Boy and Baby Girl Seabrook, Junior Miss Seabrook, and Little Miss and Miss Seabrook.

Throughout the event, a disc jockey will play music near the playground, where much of the activities for children and young adults will be held, Carter said. Field games, including a three-legged race, softball toss and tug-of-war, will take place in the afternoon.

Regular vendors will include Ye Olde Clam Stand, which has participated in Old Home Day for nearly five years, Carter said. The Lions Club will set up a tent where there will be a bean supper, hamburgers and hot dogs, Carter said.

The day ends with a fireworks show at 9 p.m., which Carter said will feature more fireworks than usual because of the 250th celebration.

“It should be a bigger display,” Carter said.

The cannon featured in the 250th parade, which kicked off the celebration, will be fired during Old Home Day.

“I don’t know how many times, but definitely more than once,” Carter said. “They said they have about 50 pounds of gunpowder. They are ready to go.”

Tickets for the grand ball and banquet are available for purchase from the Recreation Department and the town clerk’s office.
