Ok guys, I have a problem. I have a real nice gobbler patterned, but he's not playing fair

. First let me explain the lay of the land. I'm sitting in some small planted pines. In front of me theres a fresh clearcut, only about two acres. The clearcut is basically a big bottom, as in I can see flat ground for about thirty yards, then it drops off into a big bottom, and I can see the other side of the bottom going back up about 100 yards away. This particular bird has done the same thing to me twice in a row. I get there well before light, set up in the planted pines, and sit quietly til I hear him gobble off the roost. I respond with a flydown cackle and a soft yelp. Usually he answers this, and I'll yelp at him again, which also produces a response. Then I shut up for about three or four minutes. He's always roosted across the bottom about 150 yards away, and I can see him come out of the woods at this point and strut down into the bottom. He usually gobbles four or five times as he's coming. Then I'll yelp at him again, and when he gobbles back I'll cut him off with a loud cut, and this really cranks him up. He'll go down into the bottom where I can't see him, but from the sound of his gobbling he's about sixty yards from me. And he hangs up. He just absolutely refuses to move, and stands in that area gobbling his head off. I've tried everything I know, mouth calls, box calls, slate calls, I've even tried dragging him (moving back about a hundred yards and calling to make him think the hen is losing interest. normally gobblers give chase.) Nothing works on this bird. I know the obvious solution is to set up in the bottom where he hangs up, but I can't because that is someone elses land, and I can't get permission to hunt it. What can I do to bring this stubborn bird in? I'd really appreciate your help, because I have only one more week to kill one. Thanks.
