Anybody on the internet can be a Master Turkey hunter. As for his theory. Gobblers roost near hens. If the hens roost near the nesting areas then the gobblers will too. I don't believe that gobblers look for nesting sites to search for hens, I don't believe they are that smart. They search for hens by gobbling their heads off. I disagree about the dense cover. A gobblers whole thought process in the spring is to mate. He does that by looking presentable to the hens. It is hard for a gobbler to strut for his hens in thick cover. Not saying they wont but they don't prefer it. Again if there are hens in the area there will be gobblers but as a rule of thumb look for more open hardwoods to find strutting gobblers. JMO
