You will probably see more whitetails than mule deer. I hunted just north of there a couple of years ago and the guys I went with did very well on the elk. They took 3 bulls the first week. The moose are fun to watch. If you have a rifle I wouldn't worry about a side arm. My dad took a huge white-tail buck not far from where you are going. The timber can get a little thick with the snow berry bushes. Your shots shouldn't be very long range unless you are hunting in the clearcuts. Are you going on a DIY hunt or will you be guided? There is a good butcher in Graingeville who will cut and vacuum pack your meat for a resonable price. (if you don't already have a plan for your success.) That is some pretty country that you are headed to. I will try to remember more if I can. One more thing, turkey season runs right up until the big game starts. You might be able to get some in if you are showing up early, just a thought.
