I'm not from N Idaho, but we do hunt Whitey's every other year in Unit 11. Plenty of deer and yes there are wolves, saw 1 last time up in 2011, but for any NR coming here I would hesitate to say there are plenty of them around during Nov/Dec. There are indeed more than we want to have, but if you come for a week or even two and spent every minute of light searching for one the odd's of seeing one are still low. The later the better for wolf hunting as the more concentrated(winter range) you can get the prey the more likely you will be to see them.
I also bird hunt deer winter range in Unit 32, and saw ton's of track's up to 3 years ago, last two years have yielded little or none even in January.
I think the wolves we have are learning to stay farther away from places they can be easily seen or where man frequents. So I think hunting whitetails with a wolf tag in your pocket is a great plan, but if your focus is wolf, wait and come later in the winter where there are less people and the deer/elk are more concentrated.
That wolf in Unit 11 would not slow down or stop at all 2 years ago as he went through a clear cut, but did once he hit the timber. People who have hunted them for a long time in Canada/Alaska talk about how smart they are. The other 3 groups I saw had no problem stopping and staring at me, but those were all before hunting was approved.
