Lots of wolves in numerous areas. Check out one of these drainages in northern Idaho, Cour D Alene, St Joe, Lochsa, Clearwater, or Selway. For more open country you will have to go south, check any fork of the Salmon, Payette, and Boise Rivers. Wolves move around a lot. I would suggest covering ground with a snowmobile, (or truck if that is all you have) and look for fresh wolf tracks. When you get into an area with fresh sign, you will need to get away from your transportation and hike into the area. My son saw about a dozen wolves last year in one week while hiking up ridges looking for cougar tracks to run with his dogs.
