i visited the columbia zoo today and saw a sign at the entrance that stated "no food, beverage, or weapons allowed." that's all it had, no picture of any kind. is this a legal sign that must be followed? I was unsure so i went back to my car and lock my gun in the car safe. if i had ccw inside the zoo would i have been in violation? I did not believe that this was a legal sign but being unsure i wanted to error on the side of safefy and stay legal. thanks Wanna kill these ads? We can help!
