Private land will almost always provide better hunting than public land here. Habitat diversity and agriculture are the keys to deer production. Most of Ohio's public land is forested or otherwise 'wild', with little to no agriculture on it. It tends to support fewer deer per square mile. Then consider that a lot of firearms hunters head for public land to hunt. Throw in a bad to nonexistent acorn crop this year, and you have a recipe for seeing few deer in the mature woods.
One other thing that's happening is the weirdness of the rut. Deer sightings can go from zero to off the chart (and back) in just a few days. This is a hard time of year to get dependable hunting on any stand or location.
