Not to jump topics but here is an analogy....
When visiting Texas in the fall you will see restaurants offering hunters breakfast specials, hunting banners across main street and rifles in every truck window.
I live in the politically correct Northwest and if a rifle was spotted in a gun rack of a Ford, someone would call SWAT.
The point here is ...in Texas, Montana and some other places, seeing armed people is an accepted thing because its common.
Here at home I intentionally open carry in public, not because I am afraid of anything but because people need to stay comfortable with seeing me enjoy my rights.
To hide this would only promote surprise, fear and scorn when they do happen to see it.
We should not hide our mining. It is lawful, serves a necessary purpose and contributes to a whole society. If we hide what we do we will only be met with surprise and negativity when they do happen to see it.
