They may not be in the field, but they may not be far off of it either. If the deer are hanging around just inside the wood line you won't see them, but they will sure see you. Don't risk it...save for an afternoon hunt.
I have a place just like what you're describing which is why I don't get any morning hunts on that farm. To reach my stand, I'd have to trespass which I won't do.

I don't like bumping them out either but like I said, many times they are NOT there in the morning. The farm is about an hour from my house, I would hate to drive that far and then not be able to get in the tree. I think a morning scouting trip would be wellworth it.
