Watched one yesterday run inside the tree line about 25yds from the open. He stayed parallel to the field the whole time. I've seen them do this several times. I think your best bet is to find a road, gas line, power line right of way, fence row or anything just big enough to get a quick shot in and setup on it. Take something you can make a quick shot with and get in there with them. They will be running just inside the edges looking for a way to get to the sound with minimal exposure. They will try to travel in a low spot or observe from high ground until they feel safe enough to commit and will almost always come in from downwind when they do. They don't go all Hollywood around here either and blaze across open fields to calls like the movies. We have more food and less competition around here, so they don't have to act suicidal to get a meal. I do pick them up in fields at night occasionally while scanning, but I usually see them before I even start calling and they are usually exiting quickly.
