Well here's how I killed this field gobbler last week. I messed with this one several times over the 1st 10 days of the NC season. Him and a buddy had 6-9 hens and would roost about 150 yards off of a 40-50 acre field, gobble on the tree, a little on the ground, but not respond to any of my calling. They would use one of 3 routes to get to the field, then spend several hours out in the field before moving into the thicket on the other side where visibility is only about 20 yards or less where they would spend the rest of day working back across the field to roost in the evening.
After several failed attempts at heading them off and trying catch them going back toward the roost I could never get on the same route they were using.
After them getting by me again last Tuesday morning I decided to go after them since nothing else seem to be working. I made a 1.5 hour trek around the south side of the field through the woods and thicket to the other side. Luckily they had not gone into the thicket yet. I was able to slowly sneek and crawl into position to where the whole group was within 40 yards and waited until he strutted through an opening for a 32 yard shot at about 9am. I would have rather called him up gobbling and strutting but he had made me mad and he had to pay.
