While on a road trip with my kids a few years ago, we happened upon a restaurant that had audio books available for rent. Simply pick up the audio book of your choice at one location, and drop it off at another location. We tried it, and it certainly did keep the kids quiet for a few hours…this was in the days before DVD’s in cars, of course! My only issue was that the store we picked up the audio book from had a limited selection - perhaps 100 or so titles to choose from. By comparison, here’s a site with audio books that features a huge selection of not just audio books, but ebooks as well. In fact, they’ve got over 190,000 ebook titles that can be read on your Palm Pilot or as an Adobe PDF. Instead of paying $9.99 or more for a paperback in the airport, you can buy an audio book like James Patterson’s Four Blind Mice for UNDER $5! For someone who always has to have a book to read on a trip, like me, this site could be dangerous!
