I have been there and sympathize with your problem. The way I did it was I decided I wouldn't hunt fields anymore and walked along the field and noted where the major runs were. Then I followed them into the swamps and tried to get a place back in the swamp that was along the best runway. It worked and I now only hunt back on the runs. Morning is a little different and I can hunt some of the same places but I have to find a way to get to the stand without going through the field. Do some experimenting and you will be happy I guarantee it. Good luck.
