cubschris: Well, I understand why the cache was found out in the open. The old log in which we hid the cache has deteriorated as rotten logs naturally do, exposing the original hiding place. Thanks, Tarzan, for re-hiding it, but I couldn't find it anywhere on my visit to this park today.
In light of the evidence of muggle activity at this location, and lacking a suitable alternate hiding spot, I've decided to archive this one. Thanks to all who sought it.
