Cost, dies are expensive and they wear out. A lot of states don't do them in prison anymore as well, they farm them out to contractors. Somone took offense at my remarks about meeting bubba. Just to clarify I had a friend in the '80s do a bullet @ San Quentin for altering the plate on his bike. He took a magic marker and made the 0 look like a piece sign. I guess the officer and or the judge or jury didnt see the humor in it. That is certainly a lot less than changing the color of an entire california plate. Like I said earlier I am not privy to the current legal climate in good old sunny California. Maybe with the legalization of marijuana they have gotten soft. I don't think that is likely but maybe.
