Glad to hear that you pay LESS for ham plates there. Here in Taxachusetts, ham plates cost MORE, and the fee is yearly, not every two years like the regular plate fee is charged.
Ah, but in Mass. we at least get a nifty lightning bolt through the middle of our callsigns, a symbol no other type of plate has. It does cost more than a standard plate (which is why I don't have one at this point), but it costs less than a vanity plate, which is considered a separate category here.
