I agree with what DoubleLung said, but it is not a good idea to enter from a field if possible. Keep your impact as low as possible when entering and leaving. Use natural features, such as drainage ditches and creeks to disquise you and your scent on the way in. If the mast crops produce for you this year, you should be in for some good hunting. Set up between the oaks and beds, but closer to the beds in order to catch deer during legal shooting hours.
