Not bad, huh? Although Indiana was a U-Haul, so that sort of felt like cheating. I'm still keeping my eye out for a proper Indiana plate.
Ken saw Maine yesterday, but I didn't, so it doesn't count.
I wasn't originally shooting for DC, but I saw a bonus DC plate last week (and got to talk to the guy whose car it was, because I was pointing at it and excitedly saying, "Look! DC!" as he walked up).
Hawaii isn't actually that uncommon here -- I'm a little surprised I haven't seen one in a month.
I've also seen plates from [Beautiful] British Columbia, Baja California (quite common), and also Sinaloa, a Mexican state I haden't seen before.
Some of these last few are going to be tough, though. Rhode Island? Delaware? Good luck with that. At least San Diego is a tourist destination.
Also, this is a stupid hobby for someone with eyesight as bad as mine. But it's been kind of fun.
