Look at the picture of the '30.06' sign on the HP property in Houston (link below). It has language that basically says 'weapons prohibited at HP', probably making carrying a handgun under HB1815 tresspassing (PC 30.05) and then it goes into the 30.06 language on the same sign, covering a CHL holder. In this case, I don't think the new law helps, I think this sign covers both.

However, the Richardson HP sign (same thread) is 30.06 language only, so you may have a shot there (no pun intended) using HB1815 to carry in your vehicle, but I would guess not. I have a hunch that a CHL holder will end up being bound by 30.06 it that case, but that remains to be seen. Even if not, a simple ghostbusters on a compliant 30.06 sign would make any carry tresspass (except, LEO, etc.).

This is my view at the moment and, of course IANAL.....
