I work out at 24 Hour Fitness and on the membershp policies paper I got it says "No weapons of any kind are permitted in 24 Hour's Facilities." But they don't have any type of sign on their door saying this. Can I legaly carry in there being that they don't have the proper sign on their entrance? I don't plan to carry on in there but rather keep it in my back pack locked up in a locker. I don't like the idea of leaving it in my car while parked outside at night.
