GMMAT, had a similar thing in Md. except they were corn fields. They'd bed in the small corn field while it was still standing and then get up and browse through a hedgerow to the bigger field. Eventually after dark they ended up in an alfalfa field the other side of both. When the corn got cut they come out in the small field but didn't stay in it long. They'd get right on through the hedgerow and into the bigger more open field to feed. Eventually again they moved on to the alfalfa after dark as it was near a road. The one constant, is they were much easier to predict coming into the small field. Once they hit the bigger field they could go a zillion directions and did. Oh they had their prefered trails and little dips and rises they prefered, but nothing was as predictable as where they'd enter and leave the small field. Bucks will be right near dark if not after dark and have their own little routines. You're more likely to catch them closer to the beds, both coming and going,which is the small field. There's safety in having the woods close, but they seem to want to get out where they have more options. I'd hunt the small field, see what they do and go from there. They have their favorite routes.
