Down this way (Al.), the Easterns like big woods fine. Especially with a clean under story where the Gobblers can strut in the open and tall trees for roosting. And often they will roost near a creek and pitch to the opposite side. But not always !
You already have gotten off to a great start by locating a roosting area. Typically, the same group of turkey will use the same general 3-4 areas for roosting night after night. A great way to determine if the roost is being frequented is by the accumulation of poop. But if you have heard them fly up, that's even better!
Here's a suggestion - ease into this area the evening before the morning hunt. Don't get too close. A couple hundred yards or so should be close enough. Listen for turkey flying up. Or right at dusk hit a owl hooter and listen for a gobble. If you are close enough to a roosting Tom, he's likely to gobble. Now you'd know where to start in the morning.
Slipping in quietly is a must. Listening is a must. If you can luck out , the "natural" owl may get the gobblers fired up come daybreak. If you have not heard a gobbler, shortly after daybreak (15-30 minutes or so) try to shock gobble one with a owl hoot or crow call. Good luck and keep us posted.
