Not like I'm an expert like some of the turkey killers on here, but I've heard it's easier to get a bird to come up a hill to you than to try to call him down the hill. I've also been told that it's so hard for hunters to figure out what they are going to do because turkeys are so dumb even they don't know what they are going to do 30 seconds from now. I just try to set up where I know they've gone in the past and hope they do it again. Usually they don't but that is why I enjoy killing them when I can get it right.
