You WILL make yourself a target for burglars who'll try to break into your house or car looking for those guns you want everybody to know you have.
^^ That's a very important point.
I live out in the country, and don't *mind* if my neighbors see a gun on me. I shoot handguns off the back deck frequently, they all know I'm a concealed carry instructor, etc. (Most of my neighbors do likewise...)
I do NOT put bumper stickers on my car, "trespassers will be shot" stickers on my house windows, etc, because if someone randomly goes driving past my house I don't need them knowing. "Steal me stickers" is what those were called back in the 80's-90's - referring mainly to car audio equipment (Alpine, etc). It lets the thief know "there's something valuable in here."
An NRA sticker on the back of your truck makes it a target for a random thief to smash in to while you're inside eating or shopping.
A "Protected by Smith & Wesson" window sticker on your front door signals any thief who happens to see it, that you've got guns in your house. Couple that with a stakeout or if there happens to be a stack of newspapers sitting there, and the grass is untended in your yard... then they know you are on vacation....
Now if I'm outside and a random car goes by (unlikely as I'm on a dead end), and that person *happens* to notice the guy in the yard is wearing a gun... well, nothing says "don't mess with this neighborhood" quite like that. Would be a bad idea to hit an occupied house out in this area.
Unoccupied? That's what the big 3600lb safe and other home security measures are for.
When I go in public I have no choice but to carry concealed, IL law stipulates that. And I do a good enough job at it.
But, given the *choice*, I don't *mind* carrying openly. In fact, when I travelled to the East Coast back in 2012, not having any sort of concealed carry permit, open carry was the ONLY way I could carry in Virginia and North Carolina.
I had no problem carrying openly there, didn't feel awkward. With it being my only choice available, I'd rather be armed and open, than disarmed.
