A few weekeneds ago, Scott and I ventured out to a park in the middle of Chicago. It houses a recycling center (which is the actual reason we went) where you can drop off all of your recycleables. I noticed this shed and was intrigued - it is a book exchange. You can bring books that you no longer want/need, and pick up a new selection. The titles were kind of strange (so this wouldn't be the place to go to check out the new John Grisham!) but I think it is such a cool concept.
