Specifically, I'm wondering about the Selway-Bitterroot range area that's about 2/3rds in Idaho, and 1/3 in Montana. I'm going to move to one of these states in a few years (or Wyoming), and I'm trying to figure out, if I live in MT and have a lifetime license there, and go into Bitterroot, am I allowed to wander over to the Idaho side in pursuit of elk, etc. (or vice-versa). Is one of these two states more lenient than the other about letting license holders from the other states wander onto their state without a license / tag from their state? I cannot find anything on this after doing some searches....
