I killed one last week at 5:30 that was gobbling like crazy. The first bird I actually had that gobbled at my calling this year. He was by himself at the end of a green field and gobbled at a crow before I got to the field. I set up and called and he went crazy. He hung up for 30 minutes in a low spot and I couldn't see him, but with some aggressive calling followed by silence he had to check me out. I killed him at 42 steps sneaking through the tall grass in the greenfield.
