That is usually what I do; that or play video games. I remember one trip where we were able to hookup[ my gamecube to a vhs player thing in the car so I played Pokemon Coliseum on a two and a half hour car trip haha.
On a lot of games, I don't even have a Flying type to use Fly, which is strange. xD
In other news, I'm going on a road trip and am trying to learn to read Japanese. :D We're going down to California, and on the way I'm gonna read a book I bought and try and learn to read a basic form of Japanese that's in games like Pokemon, Mother, etc. Along the way I shall test my skills by playing my Japanese Mother/Mother 2 and Japanese Black.
