There is so much to learn to call them in for a shot in Pa...However you do have to pay your dues...IMO...I now hunt with the wind in my face.. I just get legal 25 yards from vehicle, I use objects out in the fields to block them from going down wind of me, I use long periods of silence, when they howl and won't come in.. I use one full minute of the Coyote Pup distress and then I shut up for 8 min.. I don't shut off my shooting or head light when calling.. I turn head light off when I look down the scope of my rifle and find the coyote and fire...The light is always on the scope illuminated...then you have to know how they act to calling... None of the down wind stuff most times.. they come in to your calling with the least resistance... Watch the logging roads coming out of wood lots and paths that come down through the farmers fields... they don't use their energy up jumping over stubble corn to get to your call.. they actually will work there way back and forth through the corn stumble long ways and then cross the next row and back and forth... They will come in from your side and flank you and they will come down the roads to your calls and get behind you that way...If people are using electronics in that area you would be better off to learn how to howl with an open reed and at least be able to do your own pup with an open reed call.. It doesn't have to sound perfect either..
IMO as soon as you said you try to circle around and walk in it was over...
