Here in Montana, open carry has always been legal. Yup, from the days of the Montana Territory until now. I am not currently a member of the NRA or any other gun organization.
In fact, it is codified in the State Constitution, Article II, section 12.
I find it quite amusing that all people can see is the possibility of having to pull a weapon on another human. In the back country campgrounds around here, I am much more concerned about rabid wild animals. No, on second thought, forget the "rabid". Healthy wild animals are bad enough!
No, I have seldom encountered any, and when it did happen I did not have to shoot anything.
But, as others have said, I have never needed a fire extinguisher or a first aid kit or an axe, bucket, and shovel or a spare tire, lug wrench and jack or a lot of other things that some say "are just good insurance".
"Good Insurance" can apply to many things. A firearm qualifies, IMO.
If you meet me in a campground somewhere in Montana, will I have a firearm? Maybe, maybe not. I will not tell you, because you do not have a "need to know".
In many places in this state, the tag line in my sig. would have to be changed to "help is hours away". Cell service is spotty at best, CB radio is practically useless, and Ham radio is only marginally better (You might make contact with somebody in South Florida, though). In such areas, it is best to be able to take care of yourself.
Good luck.
