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.
