I recently permanently archived "Bus Stop 70560" as the cache was no longer at the original position, the cache has suffered structural failure and the original position was the location of a prolific crop of Arum Lilies (weeds). Permanent archiving was appropriate to protect the lilies and allow the cache to be repaired for relocation.
