geordie: Sadly have to archive my first Sydney Cache, it was fun while it lasted.
Based on the previous logs, the cache which was hidden in plain sight kept falling from its spot, got drenched, then sadly disappeared (most likely from the rain).
This cache was near my grandparents old house before they moved, sad to see it go, but all good things come to an end.
I may place a geocache near my grandparents new house (still in Mosman) in the future, in the meantime, no more caches in Sydney.
