Most plants around here have prohibited any firearm on their property for the last 40 years or more. If found to have one on you, you are fired immediately. Course every so often some knucklehead has to try it.I live in upstate NY too. My work will fire you on the spot if you're caught with any type of weapon on premise. I have a lock box in my truck that I use before going into the plant and through a metal detector.
They can't fire you for talking about guns but in today's environment I'd be careful and stick to people you know hunt or carry.
I belong to several Gun clubs so I usually do my BS ing at the range.
When caught they like to claim their rights were violated. Idiots.
