<< Texas, where I live, allows concealed carry so be careful who you choose to rob here. You can have the tables turned on you quickly. From what I remember, Arizona had an open carry law, but it was changed to a concealed carry law. It was/is state-wide, not city. Texas penal code (huh, huh, I said penal) states clearly that if a business doesn't want you to carry in their store, they must post a sign with very specific language and the sign must quote the penal code statute. If it doesn't, then just ignore it. A sign that simply says "No guns" is not binding. >>
Not to mention that in the last session our legislators addressed the fact that every schmoe in the world was sticking the legal "can't carry in here" sign in their window. You'll notice that the vast majority of the places that used to have those signs now have the one that says "the unlicensed possession of a firearm on these premises is illegal..." (paraphrased). The legislature really cut down on the number of places that can post the 30.06 sign (the one that says you simply can't ever bring a concealed weapon in).
But you still can't carry in amusement parks, sports venues, or places that derive 51% or more of their revenue from the sale of alcohol (these places will be noted by a sign with a large red "51" posted somewhere close to the entrance -- a sign you've probably never noticed unless you went through the class, but you'll see them all over now that I mentioned it!).
I love living in Texas! We don't need no stinkin' STUN GUNS!!
(that oughtta rile up the gun-grabber crowd...)
