I've never seen a no-guns sign on any of the establishments around here.Oh, they are there, I just "don't see them."In CO they can only ask you to leave. If you refuse they can have you cited for trespass.
For now. Pretty soon the "Authorities" will just shoot you and leave you for the street sweepers.
IDGAF - I Don't Give A F--K , It's called concealed for a reason. Oh - Champs Restaurant doesn't allow guns, so I don't spend my $$ there.
