Its been a long, long time since I've checked in here.
I just read Mambear's comment (above) stating

You can open carry in most places depending on where your going. No Banks, Casinos, bats or State/Federa) Buildings

THAT IS INCORRECT.
Open carry IS lawful in banks and casinos; there is no law prohibiting open or concealed carry in banks and casinos. Having said that, they have the option of trespassing you. (And virtually all casinos do ask you to leave or trespass you.)
