So why are guns diffrent from everything else?
Smoking for example. Non smoking signs carry the wieght of law behind them. Smoking is a 1st amendment right.(yes it is) why does a non smoking sign carry the wieght of law, yet a no gun sign does not?
They are both choices you make, both could harm those around you, both you don't need to survie...
My point is you can't having things both ways, either a written notice is good for everything or its not.
