Interesting idea... kind of Czechoslovakian ( as in pre-end of the cold war), but interesting none-the-less.
Myself, I think a license plate is a fashion statement - - much like a new pair of eyeglasses, or a new shirt, or a pair of sneaks, etc. In fact, I like to switch mine off about every month or so. Number changes are fun, and that way it's not like you are having to pay for a vanity plate or somethin'.
The covered wagon is cool. I wish, however, that it was an Amish buggy like they have in Indiana or Ohio, or Pennsylvania, or parts or Wisconsin. Complete with a Caution symbol. That would be neat.
