Found this, it looks promising but how would you go about setting it? There is a dirt road that runs behind it 10 yards, this time of year once the hunters are out of the area very light traffic, three cow trails intersect right at this point

Not were a caught animal can get into the wire. Two thing I'd consider is micro location where your seeing the most tracks or sign.... road or cattle trails and the dominate wind direction. Sounds like a good junction. If I could set up wind of both the road and cow paths without being too far from both that would be the place I'd start
