There is a new set of mutlistage caches arround which you can only find if you have a team of peoples from different countries. They are called World Caches and are located in the USA, Canada, UK, Australia and Germany:
Canada
Germany
Australia
UK
USA
I've already teamed up with one cacher from the USA and we're looking for a cacher who lives nearby the canadian cache.
If you want to join our team and help us to find these caches, please send me an email to world-cache AT hulmgulm.de
Thanks!
