I use a call and a decoy but it depends where I'm hunting with what I use. Areas east of the springs I rarely use a call because a lot of people work that area and the coyotes are smart to it. So talk to the ranchers and find where they put their killed animals which is usually in their back forty and they will almost always give you access if you are respectful enough. I usually try and stay a hour or so east of the springs because with the amount of my fellow military running around trying to hunt coyotes it gets to busy for my liking. I also hunt coyotes up near Guffey where there is a lot less pressure on them so calls and decoys work like a charm. Same applies there with getting access from ranchers, I started with access to one ranch and just with the ranchers talking to each other I ended up with access to 4 ranches that bordered each other.
