I've been considering the same thing. I've done a little research but can't seem to find a good outfitter. I assume you're talking the sandhills region? I've also been looking at western Kansas, i have 3 pp's of course it's muzzleloader only for non-residents. I'll be keeping my eye on this thread as well.
www.drhuntingadventures.com I have a great hunt in NE where you can expect to see a lot of muleys every day. You can also take a whitetail if you want for a trophy fee. Let me know if you're interested and I will fill you in on all the details.
