Good luck finding any public ground that doesn't get a lot of pressure. The Corp of Engineers ground in Madison County along the river gets massive pressure each season. Your best bet is to find a good size chunk of public ground and then be willing to walk further and drag further than 99% of the guys that hunt it. I have 2 different pieces of good public ground that I hunt and rarely see others. I hunt as much as possible during the week and I am willing to drag a Deer a mile (which I have!) if necessary. You might consider the Shawnee National Forest if you're willing to drive. It is big enough to get away from everyone if you're willing to work for it.
