Northern Wisconsin in peek years have a lot of ruffed grouse. Park Falls Wisconsin calls themselves the Ruffed Grouse capitol of the world. There is a lot of area to hunt in Northern Wisconsin in the Chequamegon Nicolet National Forest. There are walking trails, and ATV trails are another good place to walk and try to get them
Having a dog is a large advantage. Especially one that retrieves. They are a lot of fun to hunt, and season starts I believe in September.
