Turkeys are more attracted to the thinned timber in general and if it has been burned, it can be really good. Learn where the best location to set up is near the edge. If there is a drainage or water near, they should roost close to it. Set up as close as possible. Many times, you will have to enter in the dark to your setup to avoid being seen.
Basically, I love hunting where the timber has been thinned , but it has it's challenges for hiding and moving. You must be more patient.
