Oilcan,
I have found, and I'm sure it is the same everywhere. If you go in an honest 1 mile from the road, you leave 95% of the other hunters behind. One mile from the road in Idaho is usually at a 45 degree angle. I have hunted in unit 39, arguably Idaho's most popular unit and very seldom see another hunter. Now I make a real effort to get away from people. But the success rates in most general units are anywhere from 25 to 45%. There is no non-res tag cap on most units in Idaho.
