On the surface, it sounds like you have alot of land.
In reality, like you suggested, that can be misleading.
Many of the clubs I have joined in the past, had lots of land, but 90% of the hunters utilized 10% of it. Mainly because the food plot was where everyone hunted, etc.
Id bet if there were 20 hunters, in ALL of the land that you mentioned, that are just average hunters, with no rules, you'd never get the kind of deer you are hoping for.
Unless you were first in line of course the corn pile.
You could lay out an arial photo of the whole area, and find that one spot....waaay back there.....
Best of luck with it,
Its so much more fun to just hunt for meat though!!
