Acorns are crucial, especially in our area. Does and bucks that are very hesitant to enter open agriculture and food plots(after season has started) can still be found rummaging acorns and not just and dawn or dusk, anytime. We have a nice oak bottom on our farm and one of my favorite scouting tricks is to walk through early with binocs and see which trees are starting to hold a lot and I mark them on themap andcheck them often after that. That part is easy just walk instop and listen(and of course look on the ground). When they are falling heavy I won't be anywhere near a field I will be right in the heart of that oak flat and on the opposite side of their bedding. I wouldn't really call them staging areas because if the acorns are on the ground that is their destination feeding source, I usually don't see them holding up there and then entering a field, I see them feeding through the flat from thick cover to thick cover and sometimes to water.
