Yup, that one of the needs of proper land management.... deer need "Cover". A deer can and will vary well bed on a ridge top where he can see and hear any trouble coming.... but they do need some hideouts that are thick to really hide. Deer will travel a distance for food. If they have to travel a bit of a ways for cover they will do that too. It depends on the time of year. Right now they'll use a corn field or bean field. They don't need a big space. They'll bed in cattails, grown up grass and brush, just about anywhere. I don't think you necessarily have to make such an area but select one thats close to what they need and stay out of it. If you keep walking in they'll move to some place new, like your neighbors land. Nothing wrong with deer bedding across the fence line and coming to your side to eat.
