3 year old cut over is just starting to get thick, and if it isn't replanted it's even less thick. If they can't see you walk in still they probably hear you. You need to have a way you can hunt from the edges because trying to set up in the middle of a 40 acre piece will guarantee you run everything out. I've hunted a spot like that and it's usually an all or nothing deal. Either you get in and set up on them, or you run them off to the next property. If you run them off consistently deer will pattern you in the drop of a hat and the piece becomes nearly unhuntable.
