It is time to introduce my daughter to the wonders of The Hitchhiker's Guide to the Galaxy.
As you likely know, the Hitch Hiker's Guide has already supplanted the great Encyclopedia Galactica as the standard repository of all knowledge and wisdom, so I really ought to familiarize my kid with it. This unabridged audiobook, read by the always amazing Stephen Fry should do the trick nicely. We have a 6-7 hr road trip.
I hope my kid knows where her towel is at.
