I know the public land I hunt fairly well, but the last couple years the DNR has gotten more proactive with their selective cutting and crop planting - so there is always something new somewhere to check out. For example, this year I found the ridge that I hunted last year was almost completely clear cut and and there was another field (formerly field grasses) that is now planted with corn. I was a little surprised when I saw it earlier this year but after some quick snooping around it looks very promising. So even though I know the land well, there is always something new for me to investigate.
