Being a Victorian I thought I would have no hope ever logging this locationless as all our regular number-plates are three letter three number combos (except for the uncommon and expensive custom & Euro style ones) But in the city for some training (and some geocaching of course) I spotted this NSW-plated Hyundai van in the central Queens Street parking strip, and even luckier it had unclaimed element #62 Samarium (Sm) as the last two letters on the plate
