Due to its location along I-95 on the Massachusetts-New Hampshire border, Seabrook has many fireworks 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 where Massachusetts State Police have entered New Hampshire in efforts to crack down on transport of fireworks back over the border.[6]
