If you know a bird was/is in the area and can hear your caling, it can be worth waiting a long time at one position. That late in the season some birds will come in very slow and/or quiet. The old method of calling soft & sparingly, and waiting a long time can pay off this late in the season.
If the birds are fired up hunt them regular, but if they seem quiet and reserved you can try the slow method. Not real exciting and it can test your patience, especially with the bugs. But if a gobbler comes in drumming then it is exciting! [8D]
