The town of Seabrook has historically been known to have an accent unique to New England and even the surrounding towns, colloquially known as the "Brookah Accent". Sources have described the accent as reminiscent of ruralEngland, particularlyYorkshire, accents. This is believed to have been influenced by the relationship between Seabrook and towns in Maine due to the shared fishing-based economy.[6] Others have claimed that the accent originates fromElizabethan London through colonists entering America, which was preserved to an unusual extent in the town. This leads to the claim that the accent is particularly similar toShakespearean English, which can be sparsely found in a few American states today.[7]
Due to its location along I-95 on the Massachusetts-New Hampshire border, Seabrook has manyfireworks and fireworks supply stores;consumer fireworks are legal in New Hampshire, whereas in Massachusetts,they are illegal and cannot be purchased. This creates a demand for fireworks in border towns like Seabrook, to the point whereMassachusetts State Police have entered New Hampshire in efforts to crack down on transport of fireworks back over the border.[8]
