Being from Southern Illinois, I love the 5th season where I've taken my largest birds. A lot of the mating is over and often only the boss gobblers are still looking for straggler hens willing to breed. My experience is that they still expect the hens to come to them and will periodically gobble for a couple of hours after fly down. My most success has come when, after 20-30 minutes of occasionally yelping to him, I introduce a gobble tube which gives the impression that a strange tom has moved into his territory and is courting "his" new hen. This often creates a dominance situation which, after another 20-30 minutes, brings the real bird in which by now is in a fighting mood. Last year's 5th season brought in a gobbler that was barely in hearing distance at daylight. I often take a black powder gun because the shots are often right at the decoys. Best of luck in your hunt.
