Cow Spots: After long contemplation, I've decided to archive this one for good. Many of the caches in this general area have tended to disappear, for a variety of reasons. This cache either disappeared due to weathering or human activity nearby. I haven't been able to find a reasonably secure location nearby to justify re-enabling the cache.
It's a pity, since this is one of my favorite puzzle creations. But it served its purpose for the time it existed, and I think most solvers who really wanted to find it had already succeeded.
