Signs are not legal or illegal. There is nothing making that sign not legal. The question is enforceability.
You know what he means
What is the problem with it?
Text size?
Location?
The language is not identical to the required language, and part of the sign is covered up
Damn, I read through it checking for that, & thought it was.
ETA:
Is it the (parentheses's) missing?
Yep. lol. Statute says it has to be "identical"
To me, that sign is telling me to eff off, regardless of how I'm carrying, or even if I'm carrying.
