I have seen bucks that big in Iowa, Nebraska, and Ohio. Iowa would be my top choice always. But I hunt with an outfitter on some great ground, may be looking at a diy in Iowa though. It takes 3 or 4 points to draw an archery tag in zone 5. I've never seen so many older bucks in 6 days of hunting. I've hunted Iowa 3 times and it was great each time, well worth the wait if you have good ground to hunt. Haven't been there since 2011 though, not sure how much ehd effected the area I hunt.
Ohio can be a great diy hunt if you are willing to put in the work. Tons of public land and good camp sites, cabin rentals, etc... I haven't seen a lot over 150 but usually see at least one each trip. Lot's of big hills and rough terrain in Southern Ohio, pretty easy to get away from the crowd. But you don't generally see very many deer back in the mountains. See way more bucks than does.
Good luck in your search.
