@KanKan : When I was in Ohio I tried for Gammy but that was taken. Since I had two grandsons I tried for Gammy2 but that was taken too. I ended ordering a custom frame that said "Nick's and Luke's on top and Gammy on the bottom. I had a vanity plate on one of the classic cars we owned.
I was told (correct me if I am wrong) that vanity plates are purchased for 5 years. Last time I looked it was maybe $500 +. Now if that is the case and it is good for 5 years (or do you renew every year?) and you would spend that much at least on the tag/sticker over 5 years of regular sticker.
