Is anybody else hunting on the island? Have you seen any turkeys on the island within the last year or 2? Do you have any game cameras up? Are you seeing any sign of turkeys? What kind of locator calls did you use? What style or method of hunting are you using? Run and gun (like spot and stalk)? Camo out and sit still using calls? Hunting from a blind? Are you using any decoys? A lot of questions but your situation is intriguing.
