You get more letters in those states. Wisconsin has limit of 7, and it used to be 6. And the answer is no not casino related.

My current plate is Sportscar Racing related. "SCCATNS" It used to be a bus from Kenya "MATATU" for a long time the second car had "PORRO" and then I had the road rally car with "HODAGS"

Down to one car, so that limits the fun and money I can waste on personalized plates.
