[QUOTE=after open carrying several times through the mall next to my house, security informed me of no guns allowed in the mall, not even concealed, they were polite, told them I could not see any gunbuster signs and they said they're "on the side."[/QUOTE]
Welcome to Utah.
Just in case you didn't know, "No Weapons" signs do not carry the force of law in Utah. If they became aware that you were concealing, they can only ask you to leave. If you don't leave, then it becomes trespassing. Happy carrying.
