I'm looking at the possibility of doing some "damage control" hog hunting on some land by where I work in the hopes of opening up several hundred acres that I can coyote hunt on. A coworker and I have discussed it, and he is in the process of building some hog traps, buy I would really like to call some in. I have a Johnny Stewart e-call and was wondering what types of sounds I could try; also, is this safely done sitting on the ground, or should I try to get elevated somehow? Any advice would be greatly appreciated. Thanks ahead of time.
