You guys in TX need to change your laws to those like in UT and ID. “No Firearm” signs in Utah and Idaho have no force of law unless they are posted on property that is specificallymentioned in State Law as being off limits to those with a Permit/License to Carry. In Idaho that is a Jail or juvenile facility, courthouse, a public or private school (UT allows guns in schools...and I believe ID now allows permit holder in college to carry). (Not counting Federal Facilities.)
But, if they see your gun, and ask you to leave, you MUST leave. However, if they call the police and they didn't ask you to leave, the police will just ask you to leave.
And never saw a no gun sign in UT, the entire time I lived there, and so far, have not seen one in ID.
And when I was a lot younger, and in 'Nam, I learned never to give a can of gas to a Buddhist. So keep the gas away from Ray....
