UPDATED 7/12/2014:
The original cache was a black bison tube on a payphone at the edge of the parking lot of the old castle.
The new castle was pretty far along in its construction at the time the original cache was hidden and it seemed that my cache host would not last long. And yet it did, serving for about three and a half years, a good deal longer than I expected.
The cache was moved on 7/12/2014 due to the changes at the original GZ.
There is always some way to leave your mark on the log. Future logs that indicate the finder did not sign for any reason (no pen, log full, pack of wolverines scared me off, etc.) will be deleted.
