well I am a food plot hunter in my home state, BUT I have hunted in many states including Ohio, and OHIO public lands have lots of state installed food plots, so you can still hunt food plots on public lands
as for deer leavingfood plots to eat acorns, well NO and YES, here at my place deer feed in the food plots all yr no matter what other crops is on the ground, but acorns will change the timing some what, as deer live mostly off my property, and when there is NO acorns they pretty much come straight from bedding cover(off my lands) and walk real fast straight to the food plots with few if any stops
when there are acorns, they stop and feed on the way, making many deer not make it to the plots till after shooting hrs, but they always still feed on the plots, just many times at night
thats the bigger problems with plots, deer know there there can come at any hr fill up and leave, and many prefer to feed at night being so open, making acorns more attractive
I think when there about, as there is cover in the woods for them to eat, in a safer feeling
with the cover about, and I am sure a change in diet is a welcome thing for them as well
but food plots will always pull deer, like candy to a kid!
