I was hearing coyotes closer to my home than I cared to have them. Having a few friends who also didn't have a lovable relationship with coyotes either we set out Right here at home and did well. Then one day one of my friends was at the mill getting some feed ground for his horses heard a couple farmers talking about coyotes in his feed lot.
John volunteered our services to help rid the problem and we have at least 5 farmers call us every year asking for us to come see what we can do, all word of mouth.

So I recommend you start knocking on farm house doors and asking about hunting coyotes on the farm. Many farmers will let some one hunt coyotes that wouldn't even think about allowing you to hunt deer.
there is a learning curve even if you start out with a E caller.
