I also like to get to my area farely early in the evening also so as not to disturb there normal routine to there roostsite!If I roost a bird I make sure to do what I can to determine which tree to grove of trees that particular bird is roosting in!It does me no good just to hear a gobbler at a distance,because in most cases I can accomplish the same thing in the morning!But determining what ridge,canyon,hollow,or grove of trees he' s in gives the hunter an opportunity to get in close,or headed in the right direction!Like TurkMan I also like to let them gobble on there own in the evening and hopefully listen to them wake up in the morning!!!
