Well I agree that most of SE ohio is rather hilly, but there are still many farm lands, and food plots onn many of the public huntig area's
and the easier spots get the most pressure for sure, as most folks like the easy accdss, in and out places!
But Morgan/Athens co. And there bordering counties, all have some great public area's and hold some slammer bucks, but again, so does almost any where in Ohio.
In Or near Nielsonville is the Wayne head quarters, and its a great place to visit, they have great maps for free, the rangers there have always been nice, and who knows what tips they can tell you about where to try, I would strongly suggest a visit there if you travel to that area.
You can ask about farmers in the area with crop damage, or that might allow access if asked?
and like I said, Google earth is a great tool, to look at things some what before going?
find several like spots, then go and look at them, that is always best, as it will show elevation(hilly or flat), water and farms near by,houses,and so on, saving a bunch of time walking some what, and a head start on where to look once in Ohio!
