I spot some more....
I'm starting to realize that there a disproportional number of CXK ("Chick") Prius(es) out there. I might have to start resorting to a number scheme. I saw a silver "1" today and a Red "9". We'll see how well that works.
I have also seen:
Red "Seeks" - a Red Prius with CEX on their plates (I would use SEX, but is seemed wrong)
Blue "Seeks" - a Blue Prius like the one above
Black "Numbers" - a special state plate that uses only numbers
And a Blue one with something like "BPO" on their plate, but I'm not exactly sure.
I also realized that I've seen at least three more that I have not documented... mainly because I can't seem to remember them by the time I get to a computer. Oh well, I'm doing pretty good so far.
Oh, and I've also seen a Ford Escape Hybrid today (didn't get the plate) and last week I saw a Honda Hybrid, an Accord I think, but it was before I was looking for plates. I'm also aware that Nissan makes a Altima Hybrid, and I saw a Camry Hybrid (at the dealer... I guess that's cheating a bit...)
