books on cd rock car rides!! You can find tons at the library! Also, I found with a long trip to Florida when my daughter was 5 she & her big brother had a blast with pipe cleaners! They made such cool things & they clean up easily. I'm not a fan of dvds & cpu games in the car, kids need time to tune out & look out the window, everything is in their faces to entertain them all the time, being a passive rider can be a really good thing. :)
