NESTLED ALONG THE CLEAR BLUE STRAITS BETWEEN the great lakes called Michigan and Huron is an oblong and verdant island. Centuries ago, the Chippewa and Ottawa tribes named it Michili-mackinac, or "the great turtle." Referred to today as Macki-nac but pronounced "Mackinaw," this tiny land mass attracts tourists by the millions seeking its calming waters, grand hotels, attractive vistas, bicycle paths, and tons of a sticky, sweet confection made of butter, milk, sugar, cocoa, and a touch of vanilla, called Mackinac fudge.
