Keeping kids entertained in the backseat of the car is a challenge.  When my sister and I were little, my mom used to speed up on a particularly bumpy stretch of the Hutchinson River Parkway so that her VW Beetle would bounce, and our heads would hit the roof of the car.  Back then, it was a riot.  Today, it would probably result in a call to Child Protective Services.  I don't have kids, but if I did, I would definitely get Tales2Go.  For $24.95/year, you can stream great audio stories that will make your kids think, laugh, giggle and ask questions.  Browse and select stories by age, story type, length, publisher, and user ratings, and you can bookmark your favorites.  I highly recommend it — especially for those of you who might end up seated near me in an airplane.  Read more about it at Tales2Go.com.
