Pressman, I feel your pain I'm in KY and my best success comes from hunting around chicken farms, there are a plethora of them in central KY. I feel your situation is similar to mine:
1) A lack on coyote in the area at the same time you are, I've got pics of them in the areas i hunt and i try and get there before they do.
2) If they are there they've heard calls before
I use the craziest nastiest sound calls i can get my hands on, i've modified hand calls both open and closed reed and use mainly the loudest calls i can find. I feel the yotes have trouble hearing my through all the woods and hills which I'm usually hunting. I have a foxpro spitfire
and will alternate between stands which calls i'm using, as well as howling on some stands before i start the rest of my call sequence. My general conciseness is if they're in the area they'll come in. I do the best i can to control my scent and try and play the wind. I've hunted these critters for about 10yrs now. If you can get a spot with limited water supply and just sit and watch that maybe the ticket, i've killed several coyotes while deer hunting and not making a sound, i like to set up in large field corners where some tall grass or grown up fence rows connect with a thicket that's seems to be the ticket for them in my neck of the woods.
-Some days they just win... but when it works out in my favor i'm the baddest mother in the woods for the day-
