Location, location, location....when I rattle in my local areas here in PA, no matter 10/20 or 11/20...pretty much everything in earshot runs the other direction
same exact sequence, same exact antlers, on the place I hunt in KS on the same exact days and I will bet my annual salary I will see an animal...might not be buckzilla, and might not be in range, but something ALWAYS comes to look...for this reason I am very strategic where I rattle more than when I rattle...I don't want to be in a location that can been seen from a great distance...I prefer corners, edges, below knolls, oxbows, etc...anything that forces the them to get into my field of view to investigate with their eyes as I tend to do all that I can to keep the wind in my favor...every buck that I have killed, that has come into the horns, has been killed while attempting to get downwind. I do what I can to use the terrain and habitat to create situations that foster that movement....I have had several coming straight into a can bleat and/or grunt...wind didn't really matter.
