RE: patterning flat land big woods deer.
Just b/c they are acorns don't mean that they are prefered acorns....find the white oaks...they will eat them first then move to other oaks such as pin oaks...
i am sure that your area has been logged at some point intime so its not thousands of acres of nothing, but oaks...if it were like that, ARK would be the deer cap. of the world...so try to find the white oaks that are dropping.
i am hunting an area like you described right now.....and thats how i am hunting it. its public land and out of 6 sittings i've seen 12 does and two bucks. all within bow range. i go through and find what white oaks are dropping and i park my rear in a climber or lock on 20-30yds from these trees.
