Despite the DVDs, handheld games, music and snacks, it always feels like it takes forever to get there. When your passengers start to get antsy, it's the perfect time to pull out those games and activities that only work on a road trip, like the license plate game where players create words with the letters on a license plate. Depending on their age, your audience, who at first may be reluctant to participate, will probably join in on the fun of games like "I Spy," "20 Questions," and "The Picnic Game," which requires players to name in alphabetical order what they will bring on a picnic [source: Tellem]. The good news is that these engaging games don't take up valuable space in the car. They just require enthusiasm, imagination and brain power.
