I don't look at pressure in a statewide sense. One area, say 2 sq. miles, can be heavily pressured, while just a few more miles away the pressure can be MUCH less heavy. This is my experience at least in Central IL. It seems that around here there are a lot of small(relatively) properties with hunters on all of them, with every once in a while a large, secluded tract with very low pressure that becomes a 'local' deer hunting utopia.

This is how it is with myself and a friend of mine. We scout together, hang stands together, and have very similar hunting styles. I hunt small pressured grounds with other people/neighbors nearby, he has a lot to himself. These 2 areas are roughly 15 miles away, as a crow flies. He sees the same large deer throughout the season, I rarely see the same bucks twice. We're in our mid 20's, he has 5 deer between 125-150", I have 1.
