I hunted there for many years and always got my elk. You don’t have to look for areas miles away from roads. IMO, not all miles are equal. All of the elk I killed were within 1/4 mile of a road. However, all the roads I hunted near were closed roads. I have found well used wallows 20 yards from closed roads.
Universaly, I always find that most hunters won’t get more than 1/2 mile from the closed road signs. Hike one mile on a closed road and you might as well be in the wilderness. You will almost always be all alone.
The real problem I have found in the last couple years are guys who hike into an elk rich area and camp there. They are only a mile hike from a closed road sign but camp in the bedrooms or dinning rooms if elk. This empties the area. To each their own but, if you find people camped, simply move.
During your archery hunt, you can drive the roads and chase bugles. Once rifle starts they will go silent. Also don’t forget to use your senses. I usually smell elk and hear them before I see them.
Good luck!
