I've got a third version here. We looked for a plate with the letter "A", then "B", and so on. After "Z" came "1" through "0". Whoever found the most won the round, and you restarted at "A". Sometimes we even used road signs or the non-identification-based parts of a plate.

I have played the last version.
Also, @Whalesharker, @tober is in Australia, so if you are in the US he posts on HIS 20th, but it is our 19th, okay?

Another version I've seen is to see who can spot the most recent in-state license plate (since non-vanity plates tend to be produced sequentially).
