That's true in some places. Conversely, in many places it would be grossly out of the ordinary for anybody to be hassled solely for open carry. I happen to consider that a good thing and a worthy goal for pro-RKBA folks in all jurisdictions. I plan to make a family road trip including Idaho in the next few years, and if I come through your area I will gladly be your guinea pig. I'm betting that despite your concerns and what the local police say, it will be quite uneventful.
