The sow probably isn't going to go away unless you shoot her. We had a big bear that preferred to live on our land for at least 5 years. He liked my food plots, corn and the massive amount of berries on my land and he always seemed to hang around our general area. He stayed in the area until I drew a bear tag last fall and shot him.
I also live 3 hours from our WI land, but you can make that work if you can figure out a way to get up there and bait a few times to get them on a pattern. I actually enjoyed bear hunting on our WI land far more than deer hunting, so that was a pleasant surprise and a bonus. Now I just have to wait 6 or 7 years before I can go again.
