Wynna,
I'm not sure why you don't see any front plate decals in California. (I would think they would be all over the place) But I do see them in Texas. My cousin is a Zeta and she has one on the front of her car and I know a SGRho with one on her car. I wish I could display my Delta one, but the police pull me over every time. In Texas, you have to have both front and back plates displayed.
