Seems like 30.06 should ONLY apply to the court and court offices themselves directly - EXACTLY the same as if each room was a separate building.
Paying a water bill or going to the library is NOT a "Crime" with separate buildings, AND with Texas STATE Preemption, should be the same, common roof or not.
HOWEVER!!! locals seem to be able to ignore the laws if they wish to, with NO punishment. So best to be cautious even tho we follow the laws. (Dallas/State Fair, Frisco etc.)
IT CERTAINLY WOULD BE GREAT TO SEE THE STATE PUT SOME REAL TEETH INTO THE LAW TO PROTECT CHLers FROM SOME CITIES AND CERTAIN PEOPLE WHO IGNORE THE LAW.

Again, Constitutional Carry = Best solution!
(Make note that: overall we have EXCELLENT coverage/control on the 51% signs, the TABC seem to really get things done, AND have the teeth to see that its done right and rapidly (or else!!!)). Proof it can be done.
