If your woods is thick, more times than not the birds will use deer trails in and out, and will roost not far off them 50/60 yards into the woods. Use those deer trails to get in, in the dark and move like a deer would, don't go bustin through the woods. Pay good attention to the moon, you can move a lot easier on dark nights, NO FLASHLIGHTS. I've walked in and set up beneath the tree that birds were roosted in already, stay quiet until they are on the ground, if I'm real close to roosted birds I don't tree talk. If there is a lot of under growth in the woods, you move like a snail until you get set up. The turkeys are used to deer walking in on their trails, the sound of something walking in the dark won't bother them, and you can get really close if you watch what your doing.
