For those who think it is terrible to carry a gun right out there where people can see it because it will "offend" others... I guarantee those who don't like guns don't give a fart in a windstorm if that "offends" YOU!. So why are you afraid of "offending" them?
I can't speak for other States but here in Michigan open carry has become more prevalent in the past 3 years... and it has caused many changes including retraining of police depts. in the area of the law.. and the repealing of many illegal local gun ordinances. It is rare for someone open carrying to be hassled by the police in Michigan now... all because of people having the courage to actually open carry.

There is a benefit to concealed carriers too because since the sight of a gun being openly carried has become fairly commonplace the occasional exposure of a concealed gun isn't a big deal either.
