2. License Plate Game
The Rules: When you see a license plate from a state, call it out. The player who recognizes the most state plates by the time you reach your destination wins.
This one should be reserved only for long road trips. We remember the unbridled joy of spotting one Hawaii or Montana after hours spent in a sea of local license plates. This game is at its best when you catch ridiculous vanity plates. Here's to you, "BJLVR69."
