I'm too lazy to look it up again, quite a number allow open carry, but about 40 states allow some form of concealed carry, (will issue, shall issue or may issue licenses, there are nuances to each). I believe only Vermont and Alaska are "will issue" states where if you ask you will get.
My problem with open carry is that it invites a challenge, kinda like flashing four aces at a poker game. Me, I don't want a challenge, I don't want to show my cards unless or until the challenger shows me his/hers. If they also choose to hold their cards close there may be no challenge, or there may be some bluffing, I only want to have to show my cards when the bluff becomes real, then it comes down to not who has the bigger shinier shootin' iron, but who is better with the one they have. Better to have it and not need it than need it and not have it, but better yet not to invite the need to need it.
True enough, Robert. An old friend of mine once said that they should never know you have a knife, till they feel it in their ribs...........Now, that's a bit over the top for me, but, that was him, eh.
