From a tipster, spotted on Blue Diamond. Why are they saying "kindly" if they don't want you to openly carry at all? How about posting a sign that states "please kindly refrain from engaging in a mass shooting?"
Remember, signs in Nevada have no force of law, but if they ask you to leave, disarm, or conceal, you must.
Thanks, murdering and attention seeking asshats for ruining it for us all.
