I agree that there needs to be a vibrant caching community for all sub-caches of the World Cache. Perhaps it would also be good if all steps could be solved within one visit to the respective city, to make it also suitable for tourists - perhaps even taking in a few local attractions as well. Ideally the clues could be about places or objects that link one to another other. I am currently thinking about using some clues from museums (but that would be only how I would do it here, everybody can do what they like or what works, e.g. hiding cache stages or devising internet puzzles): For example the museum of Archaeology and Anthropology has some exhibits from the Australia, Canada and the US, the Fitzwilliam Museum should have paintings from German Painters, and I will try to dig into the collections to find links to more countries. So for example if I find an Australian artifact in a museum in Cambridge, I give a clue (e.g. number or word) associated with it to our Australian Companion. The Cachers from Australia would need to put together the clues from e.g. Brazil, Germany, Portugal, the UK and the US (and perhaps some more) to get a final clue. This could be a set of coordinates or a secret email address they need to mail to and get bounced back either the log permission (for a virtual), or a set of coordinates to find the final. That would be only one suggestion how to plan the World Cache, and we'd love to hear what you think.
