          "Commack is a hamlet and census-designated place divided between the Town of Smithtown and the Town of Huntington in Suffolk County.[25][1][6] Smithtown, founded in 1665, lists Commack as one of the six hamlets that make up the town, along with Kings Park, St. James, Nesconset and Hauppauge.[1] Huntington's own history describes the town's settlement as dating to 1653.[6] A 1911 study of Long Island's Algonquian place-names by Suffolk County historian William Wallace Tooker describes the hamlet under an older spelling as a \"hamlet in the eastern part of Huntington town, and partly in Smithtown\" — the reverse of the modern balance, in which Smithtown holds the larger share; the sources reviewed here do not resolve why the description of the split has changed.[23]",
          "The name is a later form of Winnecomac, recorded in a Native land conveyance of November 1689 in which Secatogue Indians conveyed a tract \"known by ye name of Winne-comac bounded on ye north side by Witmans Hollow\" to John Skidmore and John Whitman of Huntington.[24] Tooker traces the word to Algonquian roots meaning \"good, fine, pleasant\" joined to a term for \"a house\" or \"a place,\" together signifying \"a pleasant field\" or \"good land.\"[23] Later records show the spelling shifting across the eighteenth and nineteenth centuries, including Winecomack (1787), Weno Comack (1791), Wenecomack (1795), Winnecomak (1797) and Wenea-Commack (1812).[23]",
          "Methodism reached the hamlet in 1783, when a society formed after a sermon by John Phillips, a Methodist local preacher whom James Hubbs had invited to preach after hearing him in Cow Harbor (present-day Northport); the congregation, known as the Comac Society, was the second Methodist society organized on Long Island, after one at Newtown in 1768.[21] In 1789, during the pastorate of William Phoebus, James Hubbs and the congregation built what the church's own history calls \"a neat, substantial and commodious house of worship\" on land bought from Von Hadah Robbins.[21] The congregation describes that building, still standing as the Commack United Methodist Church's \"1789 Chapel,\" as \"the oldest Methodist Church in continuous use in New York in which people still worship in the original building, with but few alterations.\"[22]"

          "The Long Island Expressway (Interstate 495) runs the length of Suffolk County past Commack, from the Queens-Midtown Tunnel to an eastern terminus at NY 25 in Riverhead.[19] West of Commack, NYSDOT assigns the single reference number NY 908K to two distinct roads under state-park rather than highway-department jurisdiction: the Sagtikos and Sunken Meadow State Parkways, both maintained by the New York State Office of Parks, Recreation and Historic Preservation.[18]"

Town of Huntington, arising from an October 9, 2018 fall on an uneven asphalt patch in a sidewalk inside a Town parking lot, the court reversed the denial of summary judgment and dismissed the suit, holding that affidavits from the Town Clerk's and Superintendent of Highways' offices, which had searched five years of records without finding notice of the defect, met the Town's burden under §174-3, and that the plaintiff had not raised a triable issue on the narrow \"affirmative negligence\" exception to the notice rule.[8][9] The same opinion cites Coventry v. Town of Huntington, 165 A.D.3d 750 (2d Dept 2018), as an earlier application of the same ordinance.[9]",
