I don't really have a good answer. I guess I just like the letter Q. It looks kinda wierd and just seems mysterious. It can never stand alone; always dependent on the U. And most states don't use Q (or I or O) on their license plates. By the way, I'm a license plate collector, so perhaps that explains my attention to such things.
A more interesting one would be "NoPlate". Someone used that in Calif and got a large amount of parking tickets because sometimes officers wrote "NoPlate" on the ticket. lol He fought them in court and they changed the way officers wrote it to NoTag or something like that and the same thing happened again. LOL What a mess.
As for my name "States Rights" its obvious. I stand for States Rights. The Federal Govt is out of control in its authority. The Southern States had the principles of the correct way this govt should be run in the CS Constitution. When I get a link I'll post it I promise. One example is the line item veto.
(This post regarding the CSA does not mean I stand for or promote slavery. Slavery was not the leading cause of the war, this argument is worn out and has been disproven. The war was over High Tarriffs on the South and the continual abuse of Southern States by the North. I am not a racist so please do not try to paint me as one.)
