The only time I have heard of a gun free zone is in the following video which tells you how to set one up: http://video.google.com/videoplay?do...53135377963040
Seriously though, never heard of these signs before. From what I understand ANYONE by federal law is exempt from the GFSZ act if they have a permit issued by the state in which they are standing. ( http://www.handgunlaw.us/documents/batf_school_zone.pdf ). Of course your state law may be more strict then this federal law, I don't know. I don't think mine is, but still a big no-no on school property, or school functions unless dropping off or picking up and don't get out of the vehicle etc. Since I have a PER-mit, just coming close to the schools is not an infraction, good thing since I live right across the street from a school.
