There are so many variables that it's really impossible to answer. Nearly all states have spots with large deer. In areas where the deer herd is managed well (usually larger tracts of land), the odds of taking a big buck are very good. In areas with small tracts of land and many different hunters/owners, the big deer tend to be a little harder to come by because people aren't quite aswilling to let bucks walk. The biggest factor influencing a deer's antler size is his age, so herds that are managed so bucks are given a chance to mature will have the biggest average bucks and the best chances of bagging a big buck.

Speaking only for Texas, South Texas is probably the most famous for its deer herd. A lot of managed land produces a lot of quality bucks. The Hill Country is also famous for its deer herd. There are more deer there, but the deer are usually smaller. East Texas isn't as famous for great hunting, but there is still a lot of great hunting to be had there.

The Rolling Plains of North Texas, well hunting is just bad. I wouldn't recommend anyone wasting their time coming to hunt here. Yep, its just not worth it. I never see any deer, and the bigs ones are just hard to come by. No need in anyone hunting here.
