tjapukai: I have been back to the site a few times since the summer and have failed to come up with a system/cache box which guarantees that the cache can't get muggled. It has gone so many times. The tree is obviously so popular for climbing. So, reluctantly, I am archiving this one. I placed a new challenge (GC1KCB3) today as a compensation. It's only about 3 miles away.
