BYOP. This is in the New Braunfels Public Library's Reading Garden, a beautiful little park behind the library. It's in a small Hide-a-Key velcro container and has a log and geocaching rules page only.
The title of this cache is a play on a book titled "The Secret Key" and also the fact that it's hidden in a Hide-a-Key pouch.
Congrats to Vinyl Slider for FTF!
