I don't know if you tried this yet, but if you go on the odnr website there is a section that has maps and listings of all the public hunting areas. Ohio public land gets hammered pretty hard, especially during deer gun season. I hunted Highland town once in deer season, your right about the crowds!We used to hunt in Jefferson county quite a bit. We would camp at Jefferson Lake state park and hunt there and the surrounding areas like Harrison and Fernwood. I never hunted turkey there but I know that there was good populations though. For turkey I mostly hunt Trumbull and Ashtabula county's. The Wayne should be good but I think it would be tough to scout due to its size and it is intermixed with a lot of private land in some blocks, a map is your friend there. Good luck, you should be able to find some good hunting in those areas, and I would try hunting during the weekdays if possible, it will be less crowded by far.
