if the reciprocity is in effect for the two states (LA has to recognize TX, and TX has to recognize LA), then your CCW (if you have one) is recognized in LA.
LA's law is that it is legal to OC, but check city ordnances with the city or NRA. for a resident of LA, your vehicle, is considered as an extension of your home, so a handgun can be carried loaded and in view, or tucked away. it is advisable tho, that IF YOU ARE STOPPED, you "notify" the officer/patrolman that you have a weapon in your vehicle.
i try to be out of my truck and waitin @ the tailgate before the LEO gets out (and "notify" him/her)..........unless told otherwise over loud speaker. then, my hands are hangin out the window until i can "notify" him/her.
as for ranges, i do not know. might be tough bein as you're that close to N.O.
