In California you are supposed to have a front plate, also. I haven't had one on either of my cars ever. You simply won't get stopped for just that. If you get pulled over for something else you might get the license plate thing thrown in too, but if they stopped cars for just no front plate, that's all they would do all day. Probably 3/4 of Corvettes and Porsches don't run one, and maybe half of the Beemers, Benzes, as well as any custom type car and a lot of the ricers. I just don't worry about it.
