Paradise Adventures with Keith Nunningcamp. Top notch accomadations, food and whitetails. I didn't use them for whtietails but I did for turkey. The whitetails on the wall were amazing and just last year a 200" double droptine was killed by a vehicle at their leases. A class act.

Another vote for Heartland. Take into consideration that I have not hunted there though...
I work for a food distribution company and about once every two weeks I will make a delivery to Heartland. The place looks like ithas top notch accomodations and all of the people that I have dealt with there are great.
Like I said I can't comment from personal hunting experience, but if I were looking to hunt an outfitter in Illinois I would choose them.
I can reccomend a great Do It Yourself outfitter in Illinois. I've hunted with him.
He has supreme land in Illinois, Iowa, and Ohio. He meets with you, gives you an aerial and a topo and lets you do all the rest. He's got some great pieces of land, including some in Pike county, Illinois.
But you have to be a do it yourself kind of hunter or you may not get what you are looking for.
