I've roosteda lot of birds, some by luck (saw them fly up but didn't know they were there beforehand), several by design (following or hunting a group of hens and a gobbler when they flew up), and several by the traditional method of listening and owling at fly-up. More times than now, with a few exceptions, I screwed up the next mornings hunt by getting too close or being busted by the hens. In my experience the hens nest apart from the gobbler. If you don't know exactly where the hens are one can easily spook them on the way in or by setting-up too close to them.

I agree it is good to know where the gobbler is by roosting him the night before, but I am no longer going out of my way to do it. I also think it is stupid to try and get one to gobble by blowing distress calls, elk bugles and other strange sounds. Why disturb the area with that?
