I'm of the opinion there are very few areas that don't get pressure anymore. With easy to access maps like OnX Hunt and others- anybody is capable of finding back country spots. Three miles is not far from the road for whatever that is worth. I've talked to allot of elk guys that have hunted "secluded" areas for a long time. And in the last few years they're all saying the same thing. Their formerly private spots now have people in them.
Hopefully someone with experience with them will chime in.
