Traffic for 2007 October 4

Yesterday when I went home I noticed the car in front of me had an Antarctica license plate. Can that be for real? I don't see how it can, but it looked real.

If it's not real, I wonder. I see lots of people in California with stupid license plates in lieu of real ones (fake Angel fans ones, fake USC alumnus ones, etc). I thought that it was illegal to not display your license plates. If not, then why even bother with license plates in the first place?
