Has anyone in Western Washington seen any of the specially-marked bottles of Sprite with the silver caps, and which advertise "Thirst Out and you could WIN!" ?

I've been looking for one, and haven't seen any in south Snohomish County. The newest 20-ounce Sprite I can find was bottled over a month ago, and has date code "JUL0504VMD."

If you've seen one of these bottles, what is the date code on it and where did you see it?

Thanks,
