Of the 7 states I have hunted, my favorite would probably be home state of Arkansas, followed closely by the Missouri Ozarks....just so many great memories from both over the years!!! I enjoy the hunting in KS and NE too, but give me a hardwood ridge or hardwood bottom any day.
The hardest? I have figured out turkeys can be stubborn any where you hunt and timing makes all the difference, but Alabama and Mississippi usually offer a tough challenge. Ton of pressure on public land, and we usually hunt early in the season. I would like to hunt after April 1 at some point. Have killed turkeys in both, but always had to work for them. But, that makes it so much more fun and rewarding.
