Mobo, the most northern tip of your boundry line that comes to a point is whereI would put my big buck stand. Just leave about 20 yards from your spot and the river. As long as it isn't a full moon you can enter your spot right thru the feed fields.(the furthest outside edge ofcourse)I have done it a jillion times in the dark. The deer will just stand there and stare at you as you walk by. I have a small mouth grunt I use when walking back. A couple of soft grunts and you will see them put their heads down and go back to feeding. Go in and hour before sun up and if you do spook a few they will calm down when they feel the danger is over. Like Germ I hunt river bottom land exclusively. I didn't just throw a dart and pick that spot. I have learned something about deer travel and proved it to myself the last couple of seasons.
