Back when I was knee-high to a grasshopper, I had a "BILL" plate in Connecticut colors for my bike. No reason there couldn't be a FIRST-themed version. Probably too late for the 2013 KOP, though, ya think?
Anyway, Logoloc are the guys to try for this, I bet. They're always on the lookout for places to slap the logo. It should come with a booklet of snappy patter to use with the traffic cop that pulls you over.
