Not every state requires a front plate. Mine presently does; but there are frequent suggestions to do away with them. In the interim, I use a GoMiniGo, and if they eventually do away with front plates, I remain un-drilled and good-to-go.
Previously, I street-drove a Caterham Seven "clubman." There is literally no place to mount a U.S. dimension plate that didn't either drag on the ground or block the radiator. I went without, but always carried the front in the boot (renewal stickers and all). I was never stopped nor had a problem going through annual inspections.
