Not really, I actually find it kind of silly. I'd have rather they let gunbusters signs stay but not have the force of law.I guess we got lucky...
In other words, as I understand it, if you carry past a 30.06/30.07 sign, you're trespassing. No further notice is required and you are in violation subject to criminal penalties (I think used to be Class A misdemeanor but was changed to a Class C a session or two ago). I'd have rather gunbuster signs but you can only be charged with trespassing if you're asked to leave and refuse.
But that's a topic for a different thread.
