This letterbox is placed at GZ. There is a stamp included in the cache because it is a letterbox. The stamp is NOT a trade item. Please leave the stamp inside the container. There is parking at GZ. It is an entrance to a farmer's field. Please pull off the road completely using this entrance. If a car goes by, please wave to them. They are slowing down to make sure you are okay. This container was given to me by a friend at an event this past spring. Please be careful with this container... it is somewhat fragile.
