I am not a fan of open carry. Where I live in Nevada it is legal as well, but I don't do it for a few reasons.
A lot of Europeans come through my town on their way to or from Death Valley Ca. A lot of them are not accustomed to seeing someone dressed like a common worker carrying a sidearm. When they see a gun, they get tense. It is not my intention to create an uneasy feeling in anyone, so I carry concealed with a permit. Little do they realize that the slob standing near them,(me), makes them safer from crime than anywhere else. Unless someone needs to know, they don't know. I do not require special attention from everyone around me. I am not saying that people who do open carry are looking for attention, but I do know that when I am in a store and I see an open carry, I do keep an eye on them. I don't want this type of scrutiny for myself.
Also, if a bad guy, (or anymore a terrorist), comes into an area carrying concealed, who is the first person that they will shoot? Yep, the open carry person looking at something else.
We don't have a lot of violent crime in my town. There are a lot of people here that carry concealed. All the local bad guys know this, so if they go into a business to rob the place, they have no way to know if they will be shot by one person or ten.
