Third Time's a Charm? Mystery Cache

This cache has been archived.

Nomex: As there's been no cache to find for months, I'm archiving it to keep it from continually showing up in search lists, and to prevent it from blocking other cache placements. If you wish to repair/replace the cache sometime in the future, just contact us (by email), and assuming it meets the guidelines, we'll be happy to unarchive it.
