The airport offers convenient access to Mackinac Island, which is known for its fudge. There's approximately 12 fudge shops on the island, and there's a fudge festival held annually in August, according to WXYZ.
Airport Manager Tami Beseau told MLive that the fudge sign is Transportation Security Administration policy, not a local airport ordinance. While candy is permitted in both carry-on and checked baggage, it may need additional screening, Beseau said. The soft, dense consistency of fudge could allow someone to slip contraband inside the candy, according to Beseau.
