Her business activities may be associated with warmer temperatures, but a Strong’s Neck resident is keeping busy even in the colder weather.

Margo Arceri is known in the Three Village area for creating Culper Spy Day, an annual event in September, and Tri-Spy Tours, which takes participants to local historical sites. While the excursions include participants walking, biking, kayaking and paddle boarding — activities many may associate with summer — Arceri said the business keeps her busy year round. This year she was booked for private tours up until Thanksgiving, and she will be sponsoring the screening of TBR News Media’s “One Life to Give” at The Setauket Neighborhood House Monday, Dec. 10, which will be hosted by the Three Village Historical Society, something she said she’s looking forward to.

“I love the storyline, and the Times Beacon has been an incredible partner with Culper Spy Day,” she said. “In general, it’s kind of my way of giving back and also supporting something near and dear to my heart.”

During December, January and February, Arceri said she thinks about new ideas for the next year. Recently, she was inspired to apply for a grant for a trolley to use for tours after members of the Daughters of the American Revolution and Children of the American Revolution traveled from Connecticut to Long Island, and Arceri conducted a tour for them on a Coach USA bus.

She is also hoping to extend Culper Spy Day to a weekend and would love to coordinate a bus trip into New York City where ticket holders can visit the Fraunces Tavern Museum and go on a Revolutionary War-era walking tour in the downtown area with Patriot Tours, she said.

For Arceri, the winter months are ideal for researching in places like Fort Ticonderoga, West Point, Boston, Williamsburg and Philadelphia. She said there is always new information to discover.

“Somebody will ask me something on my tour, and like a good detective, I’ll have to find out the answer,” she said.

Arceri said Brookhaven Town historian Barbara Russell once wrote, “Lucky is the child who listens to a story from an elder and cherishes it for years.” It’s a quote she always starts her tours with because she said she is that child.

The Tri-Spy Tours owner said her love for history began while growing up in Strong’s Neck where she would listen to the stories of Kate Wheeler Strong, a descendant of Culper Spy Ring member Anna Smith Strong who was known for using her clothesline to send coded messages to her fellow spies.

Arceri initially volunteered giving walking tours with the Three Village Historical Society and served on its board three times through the years in roles such as vice president and recording secretary. Arceri said she is always grateful for former society president Steven Hintze, who helped her launch Tri-Spy Tours, and current historical society president Steve Healy for helping her take the business to the next level.

“He has been incredibly supportive, and he’s always listening to my ideas and giving me his feedback and his ideas,” she said. “They’ve just been incredible partners.”

“Somebody will ask me something on my tour, and like a good detective, I’ll have to find out the answer.”

She also credits everyone at the historical society for always being helpful, and archivist Karen Martin, historian Bev Tyler as well as Russell for assisting her with research.

Healy said the admiration is mutual, as Arceri is always looking for new ideas and seeking to expand. He said he would love to see the historical society grow, and he credits Arceri with helping it do that.

“She has the vision to look at the bigger picture, and how we can tie things together,” Healy said.

Arceri said during her tours she intertwines Culper Spy history with fun facts about philanthropists such as the Melville family and Eversley Childs, because she said she feels that it’s important to point out that so many structures in the area are preserved because of someone’s generosity.

“I always like to stress on the tour from the natives, that people arrive here, and they fall in love,” Arceri said. “The early settlers did, the Melvilles did, and I try to make sure that anybody who comes on our tour falls in love a little bit with Setauket.”
