I hunted in Indiana from 1970-1989 when I lived there. I've hunted there a few years since then. Without any doubt whatsoever, the biggest deer I've seen in my life were in Indiana. I killed a 9-point with a bow that field dressed 265 in the early 80's. That was in NW Indiana (Elkhart County). When I killed that big'n I fancied myself a "trophy hunter". I passed up great deer the next three years looking for giant deer. Learned a lot, one of the things I learned that passing great deer hoping for the greatest deer is as much fun as hunting with a camera...for me... not fun.
My best friend hunts in Tippecanoe county, Indiana. He has bow-killed several deer over 150 and passed many more.
I didn't do quite as well in Orange County when I was manager of Patoka Lake (1985-1989) before moving to Kansas.
Here's one for you, the worst deer hunting period in my life was the 3.5 years I lived in Kansas.
The one buck rule is already producing great results in Indiana, just like here in Kentucky.
All my hunting has been and continues to be on private land. Not because deer are lacking, but because I don't want to interact with people I don't know.
