A serious comment here, but just go without the license plate in the front. I have done it for about a half year in Colorado and never once got any comment on where it was. I really don't think that police will pull over a $50,000 vehicle for lack of a front license plate. They're usually after the sketchier vehicles that don't have them and they want to search them for everything else wrong.
Speed trap police officers won't do anything about that because by time you're already past them, they will have just assumed that your lack of a front plate means you're an out of state driver.
