RE: Strange thought. Possible experiment.
I think a lot of people in the "east" feel that they have to try hard to kill coyotes because from my experience...they just don't come in to the calls like they do in the "west".
Having hunted both sides for coyotes...I can call in more dogs in the west in a day than I can in the east in a year.
I have a large farm in WV that has several yotes on it. I've NEVER been able to call one in. I used the same calls out west, and I called them in consistently.
Not sure why...but years of seeing this made me believe it. I'll just keep shooting them when I see them and waiting outside known dens.
