Thanks for sharing. I can understand your feeling of being disturbed in this area. I also live in Wisconsin and hunt grouse. I usually go to the other side of the Forest, actually East of hwy 70 out of Eagle River. I used to camp near a small lake called Bose Lake, which is near Butternut and just South of Kentuck. No one ever seemed to camp at this lake or what is really just a pond. The road leading to the site takes a 4 x 4 to reach it. I have had people drive down this old road in the middle of the night as well and wake me up in a similar way. I now go deeper into the old logging trails and seldom see many people.
