I would argue that the current Idaho license plates are kinda pretty. The red, white and blue with the mountains and everything - nice. But, they weren't always that way. If you remember, they were very green for a period of time. Here are 7 retro Idaho plates on Ebay that may make you wish it was the 80's again.
