Just because no one ever says anything about open carry to the person doing it legally does not mean they did not have negative thoughts they kept to themself; after all, you already have the "whatever" to walk around displaying a firearm, people may be understandably reluctant to speak.
If concealed carry is legal, and it is here, I just silently think WHY.
IMO it looks like the person has something to prove / chip on shoulder.
Criminals and psychos are mobile and my show up in "good" areas unexpectedly, carry accordingly.
Carry the gun you would you would prefer to defend your life with, in the off chance you have to.
