I’ll still carry. :)
Took the grand kids to the STL Zoo last month- saw the sign, carried as usual. The law states that entities may post against CC, but still carrying concealed is not a crime, just a citation (if somehow zoo folks learned that I was carrying), and then asked me to depart and I refuse and a peace officer is then called.
I like MO! Now, CCW license holders may open carry anywhere other than the several otherwise restricted places, pre-empting city ordinances etc. ( I do not OC, I like to be able to be under everyones radar-its a survival thing, not a political activism thing.
