Good luck. I did the same hunt this year and it was demoralizing. We saw many, many other hunters. There is an old burn covering a good bit of the unit that is old enough for the dead trees to have blown down. This blowdown makes getting away from the roads difficult unless you’re on a trail. Trails might as well be roads since they receive a lot of traffic. We had multiple spots picked to hunt and every.single.one was wrapped up. These were places that is was going to suck to get to. I’m sure that you could get away from people, especially if you have local knowledge but you should be prepared for everyone having done the same escouting and having the same mindset of going back deeper than everyone be else. Oh, and people hunt the crap out of the roads and easy to reach places.
The terrain is impassable to mortal men in many places, especially near the river. Super steep and rocky. Not all of it is impassible by any means, but if you see something on a topo map that you think is going to be tough, it’s probably a near vertical cliff that will take ropes and harnesses.
Part of the problem is that the unit is HUGE. You may not realize it, but it may take you half a day to drive from one point to another that don’t look too bad on the map. If I was going back, I would pick a part of the unit and concentrate on that. An example is the drive from McCall to Yellow Pine is HOURS of traveling. The drive in along the river is one of the most beautiful places I’ve ever seen, but if there is fresh snow on the ground that is a 1 lane road carved into a mountain side for miles. Pray you don’t meet someone or it’ll get interesting fast.
We had a good time and McCall is a cool town. The people we met were great. The area is beautiful and we may take our families there on vacation some day, but I’m not a good enough hunter to make it there. P.S. We slayed the grouse.
