This was 4 years worth of hunting the same public land area in Illinois.  I would go up and shed hunt in February/March each year, then go up and get trees prepped and ready in October, and then go up and hunt it for a week in November each year.  Lots of time and lots of effort was put in to kill these deer, but it can be done if you're willing to work at it.
Of course, I'm sure there are people that blind stagger and kill good deer.  I like to know a place well and have multiple stand sites for different winds in case one area is getting pressured more than it was in the past, or if the corn in an area hasn't been cut becuase it's been a wet fall and the deer are locked down in it.
I also haven't been back in the last couple years because the deer population was dwindling (EHD hit two of the years we hunted there) and the pressure was getting worse every year to the point that you couldn't sit all day without someone walking by, even if you were well over a mile back.  More and more people are turning to public land as lease prices continue to rise, so competition isn't going to lessen anytime soon.
