This Guestbook Cache is located in a little free library at a private residence on Westgate Road in Kenmore, N.Y., with permission of the owner of the LFL, of course. Little Free Libraries are mostly located in people's front yards, although the cache creator has seen a couple located in parks, and in community gardens, for example. Should you not be familiar with LFL's, they first appeared in 2009, and have "gone viral" so to speak. So too has their use for Geocaching purposes gone viral. You can read more about them on the Our History page at littlefreelibrary.org.
This particular LFL is a twofer, so to speak. It has a Geocaching.com listed cache contained inside. We're not here to give any spoilers for that cache, but we can tell you that the Geocaching.com listed cache does not involve signing the guesbook in the LFL. The guestbook is a totally seperate entity.
So to find and log this Cache on OCNA while you're there finding the Geocaching.com listed Cache, simply sign the guestbook contained within the LFL. This is a two shelf LFL, and the intended location of the guestbook is on the right hand side of the upper shelf of the LFL, as you're facing it, although we can't promise it will always be in that particular location. It is clearly labeled as a Guestbook on the spine of the book. A picture of your guestbook entry is recommended, but certainly not mandatory. Enjoy your vist, and trade some books!
