Hearing a tom gobble from his roost at dusk is great, but it's no guarantee he'll wake up singing. Bad weather, nearby hens, and any number of far more mysterious factors can mute a bird. One radical solution: Plan to set up so close in the morning that it won't matter whether he gobbles. While roosting a bird in the evening, run locator calls to keep him talking as you use terrain, cover, and fading light to move secretively toward his bedroom. Keep going till you get scary-close--say within 60 yards. Then choose a good setup area, enter it as a waypoint on a GPS, and wait for full dark to leave. Well before dawn, use the GPS to walk straight to your spot. Now, whether your bird wakes in a chatty mood or not, you'll know you're in a good position to call him in. Also, by being near enough to see or at least hear the tom, you'll know to move if he flies down and wanders off in the wrong direction.
