Over the years, I have heard from readers who want their commutes to be longer. They want to get caught at red lights. And they'll circle the block even though they are already home. All to listen to the end of a segment on their captivating book-on-tape.

Any device that counters the wearing effect of commuting is fine with me, and with vacation time upon us, I offer some suggestions about audio books.

The first is to visit the local library, where they are free.

Here are the most popular titles of one of the biggest local companies, Recorded Books of Prince Frederick in Calvert County.
