The old red Arizona style I gave you last weekend, has a unique story to go with it. AZ UNK = Arizona Unknown
Many years ago, whenever Arizona law enforcement was looking for a specific vehicle but didn't have the license plate information, the teletype would include the identifier..."AZ UNK"...meaning the target vehicle had an Arizona tag but the numerics were not known.
Being oppositional defiant and having a host of other issues, I promptly applied for a vanity plate bearing (you guessed it), AZ UNK.
Shortly after getting the red plates (one of which you have), Arizona had to re-format the BOLO (Be On Look Out) to some other type of wording, all because I wanted a unique vanity plate.
Hope the man cave is becoming more manly by the day...
