Bike Walk Virginia
Virginia is considering offering a "Bikes Belong" license plate:
Only catch is that they need 350 orders (or they'll just accept a check for $3,500 I think) by December 27. They currently have 169 orders. The plates only cost $10 over the price of normal plates. For more info and an application [PDF] visit the plate sponsor's homepage.
I've scored one each for the girl and me.
