To tell the truth, I have found that almost all of ohio besides around bigger cities produce large deer. You just have to find them, Spend time looking for them or hope they find you. As for population wise..... Idk..... Their EVERYWHERE!!
When i was younger, Every year i would take a tripe down to southern ohio, I use to always think that only the big deer were down there. well as i got older, i found out that around here where i live theres even bigger deer then down there. In my opinion, thats because like i use to, people think that thats the only place the big deer are, so everyone goes there and just ends up shooting younger deer before they could get big. So i believe anywhere around southern ohio isnt that great for size wise but still doin pretty good for population.
