I saw in a magazine lastyear that the Delaware Wildlife area is also top notch..I hunt there, it's public land..You should look into maybe going there as well or instead? I'm just up the road from it, I've hunted there a few times and I know a few spots.
Now, if you're talkin about counties..ever since that Chronic Wasting disease hit last year, the south of Ohio is low in deer population...your best bets from what I've heard are the middle counties of the state, like Knox, Holmes, Coshocton and so on.. I've driven through Knox and Holmes counties a lot here in the last few weeks and the DEER are THICK..walking up people's driveways in the middle of the day.
my two cents..
