Being an avid reader, I've spent a crap load of time in used bookstores. If there is a heaven, and if it is tailored to the needs of each individual, my version would probably feature at least one used bookstore. In light of the rather remarkable amount of time I've spent in them, I've come to realize several truths about them.
1. There's always room for Congo
2. Space might not be the final frontier
3. It's always easier to try new things for less than three bucks
4. Sometimes you can find exactly what you never knew you wanted
