The Aquarium is off limits for weapons to all including LEO city, county, state and federal. As for going in a loction where they have a posted no firearms sign, remember they can lie and say you refused to leave when asked ( malls are awsome for doing this) and then the show begins. I carry everywhere I go concealed and have been asked to leave a couple of times when I show them my ID a few have still asked that I leave saying I am not in my jurisdiction. I do so not wanting to argue and try my best not to go there again.
