Second vote for the Gettysburg area. I like it up that way, as well. I would drive 100 miles from Mitchell, and get set up in a small town. If you stay in Mitchell, you won't get that feeling that you are out on the prairie. The small towns are much better for getting to know folks in the bars and cafes. I base in Miller, and I rent a house there. It's quite a drive north of there where I do most of my hunting, but I've made some friends in Miller over the years, so that's where I go in November. I can give you info if you want it. I'm gonna spend a week in October this year and stay in Lebanon with a friend. I've never gone that early before, so should be interesting. That just a bit northeast of Gettysburg. If I were coming that far for that short of time, I'd second Zeb's advice to think about a pheasant hunting operation. The first two years I came out I didn't have a dog, or a clue, and I hunted Wenzel's Pheasant Ranch in Wessington Springs. Geez, what a great place. The hunting and accommodations were really great, and the area is really picturesque, with a lot of hills. I'm thinking that you will want to shoot your gun a few times, coming from that far away. You will for sure at a place like that. I can give you Gary's number if you want it. He ranches there along with his business. Just a great guy. They had a bad tornado there in 2014. I just went through there this November and things looked good. I think Zeb had another suggestion of a place to go. Anyway, you will have many other helpful suggestions from more experienced folks on this site. Shoot some clays before you come. The birds got a lot of get up and go out there. Good luck planning and have fun.
