I would like to see open carry pass; it is what the second amendment is all about.
It won't be the person with open carrying firearm who is the problem, it would be the ninnies who call the police every time they see a scary gun. In time and with enough 911 operator training this can be overtime with a simple, "sir, a gun in a holster is legal in Texas, have a good day." click.
As for laws and signage, I would prefer a couple state models. Kentucky has the right idea for concealed, signs mean nothing, only being asked to leave and not doing so is breaking the law. If we adopt that philosophy for concealed and allow "no guns" signs to regulate open carry but still no crime until asked to leave and the person refuses, then that pretty much covers the signage issue and does away with the 30.06.
For licensing, I would like to use Arizona as a model; open or concealed, with or without a license. Sure, keep a licensing system in place for reciprocity states, but not required in Texas to carry, easy. Heck, we could even increase the requirements for the license so to allow greater coverage in reciprocity but those who seldom leave the state are not affected.
Pipe dream, you bet. I have been accused of being a dreamer before.
