RE: Wisconsin public hunting or outfitter
I guess I have to weigh in here, being from WI most of my life.
There is lots of public land in this state. National forest in the north, state forests, state wildlife areas, county forests, etc. Almost every county has some. Yes, Buffalo county has some public land. There are trophy bucks to be had on public land, people get them every year.
Choose an area, figure out logistics, go in there and hunt hard. Public land is tough. The deer in most cases are pressured, there is sometimes competition for the best "spots". I'm convinced that a hunter coming in and applying good fundamental hunting skills, patience and persistence, can be successful. Use common sense, don't overlook the obvious. Don't be afraid to try still-hunting, or small drives. Standing can get old, and these other methods allow you to stay in the field without getting so burned out. Luck can be a big factor. A big bone head can pop up in the most unlikely time or place.
Good luck.
