Grosventrehunter,
I am by no means an expert on hunting whitetails up north, but I will tell you I started buying an extra out of state tag just for this hunt (the past 3 years). I trophy hunt for mulies and meat hunt for whitetails. I generally hunt up around Orofino or Grangeville and my experience has been pretty good. I see good numbers of deer when I go out and I fill my tag (just looking for the freezer fillers). I will say that I have seen some jaw dropper bucks in the back of trucks (they are out there). Timing wise, the rut is late Nov. However, I generally hunt the last week of the season (run up for 2 or 3 days) and I see plenty of animals. Hunting pressure can be an issue. Where I hunt there seems to be a number of folks riding their ATVs, but I like to hike, so I get away from them pretty easy. If you're looking for an easy going hunt and an opportunity to take an animal (small buck or doe)... that is no problem. If you're looking for a wall hanger ... I'm not the person to talk to about that, but it is a fun hunt.
I hope that helps and good luck!
