Good friends paired with delicious food and libations, all served up in a bucolic setting. That’s the recipe for the annual Twilight in the Garden Party. This year’s festive evening will be held at the historic home of Drs. Maureen Killackey and Bruce Pinkernell in Chatham. The 1914 architectural gem designed by Wilson Eyre, one of the founders of House and Garden Magazine, sits atop a hill with views of the Catskills.
