Similar situation for me in the Eagle Caps in '88. I let out my first locate call of the morning and get a response over by some other guys camp. Sounds like a gut shot herford. My hunting partner asked why we weren't going after him and I respond, "Those idiots over there are just learning how to bugle." He responds with, "That's too dang bad for a person." So off he goes after that awful noise and I sit down for a snack not wanting to waste my time chasing hunters. Channon gets out about 100 yards and here comes this 280 class bull walking right toward him. Neither see one another. I let out a cow call and the bull nearly runs him over coming in to me. Startles Channon so bad he drops the arrow he is carrying in his hand. I screw the pooch and kill a branch trying to make a 35 yard shot.
We heard that bull bugle every day after that. He never did sound any better. Never could sucker him in again. I tried every call in my bag, but he wasn't biting. He may have sounded stupid, but he got smart in one quick hurry.
