well since your in SW Ohio, and I hunt in Switzerland Co. in SE Indiana, I will just come over and show you how to hunt him. Seriously, right now I would do some lite tickling of a rattle bag and maybe a grunt here and there, that may strike his curiosity to see who the new guy is in the area.In a couple of weeks I would try to use a doe in estrous bleat once every few hours, but dont use it right now, its too early. wait for a few weeks and let it get closer to nov. If he is the dominate buck in the area, he should come to some lite tickling of a rattle bag right now, dont make it a full out fight. mimic two younger bucks wrestling around, sparing.I would also check the fields at first light and at last light and get a feel for where he is at. Not sure when you have seen this buck (time of day) but my guess will be an evening hunt.
