As a teenager with too much disposable income, I scoffed at the thought of going to the library for books. I would drive 30 minutes to the local Borders, buy 10-15 books, spend hundreds of dollars, and be set for a while. Now, I happily scout out what to read, put it on hold, and venture to the library to pick up my greatly anticipated next book(s)! It's a 12 minute drive, and I go once every 2 weeks. I end up driving more overall, but I'm not buying anywhere near as many books, and I'm more apt to read something I'm not sure I'll love, just b/c I don't have to buy it.
My friends make fun of me for using the library still. Goofs.
