bettsbugs: We finally went out to check on this one. Originally, the cache was placed in a cubby hole under an existing rock. We then towed and rolled another medium sized rock to cover the opening to the cubby hole. We couldn't understand why someone would feel a need to move the cache....until today.
The original fairly large rock has been forcibly rolled away from it's original location thus no longer providing the neat cubby hole we liked so much to begin with. The other rock we worked fairly hard to move over there has also been rolled away.
Such is the way of geocaching: another cache fades away like the moon....
