I have dug more or less a pit blind and hunted with good success before, but farmers arent usualy real keen on having a nice deep hole in there field. Even a pop up blind would work in your situation as long as it was left out there long enough for the deer to get use to it and not see it as danger.I stuck mine out on the edge of a field and hunted it within a day or two with good success. It was sticking out like a sore thumb but as long as the deer didnt see any movement or get down wind it was fine.
