RE: turkey stump
There are a whole lot of different variables here.....I suppose it is possible that they could have seen you, or maybe you over called, or maybe they were henned up.
As mentioned above it takes time.....trust me you are going to screw up a whole bunch of times, but just learn from your mistakes and go from there. I would really recommend going with a veteran turkey hunter if you have the chance. Best of luck, and keep at it!
