I had been thinking about it for a while. I liked the ability to carry a library, the access to cheap (and free) books, etc. As a stay-at-home Dad I was frequently called to drive somewhere and wait -- dance lessons, scout meetings, etc., etc. And then my Dad had health problems and I had to drive him to one doctor or another ... and wait. I saw one on sale, picked it up, and I've been having a ball ever since!
As we were getting ready for one recent doctor's visit my Mom asked me if I'd like to bring a newspaper to read. I told her to get with the times! I had, like, two hundred books in my coat pocket!
