I realize this is a little off-topic, but given that the proprietor is a cat person, I promised to give the place a plug.
My new favorite Saturday hangout is a tiny used bookstore up in Canoga Park called Next Chapter Books. Located at 7140 Owensmouth Ave, it is open Monday through Saturday from 11 AM to 6 PM. Phone number is 818-704-5864. They have a large selection of mysteries, sci fi, and fantasy paperbacks, but also a lot of hardbacks across various genres, generally in really nice condition. They take books in good condition in trade, of course (which is half the point of a used bookstore).
Here's the website: http://www.nextchapterbooks.com/
Check it out next time you're in the area. The owner is a very pleasant man who knows the importance of personal service and building a relationship with his customers to help meet their needs.
