Update:
Finally. Somebody took a packet of zin seeds, and left, in its place, an unopened package of Burpee carrot seeds.
Yay! Action! I went ahead and put out some of the vegetable seed packets that came with the Library, to encourage further taking and giving and stuff.
I've selected Little Free Library as something I am interested in on Google News, and have read about one being burned up in Denver ( ! what meanies! ), one in Delaware that is "lifting literacy" in a beach town there (because, yanno, people are taking books and, presumably, reading them), and that in the Basque region of Spain, the idea has spawned a cousin, to wit, the Little Free Fridge, where neighbors share their leftovers with each other! Apparently that is going well, cooked food only, and stuff doesn't stay in there for long. Kind of a potluck takeout effect?
Oh, and we are also seeing books move in and out of our LIttle Free Library. We haven't yet done any kind of dedication or grand opening or any announcement of any sort, but word is spreading.
