This cache can be searched and found like any other traditional cache...
...it can be the starting point for an international cooperation as well. This cache is just one cache of a set of 30 caches named European IMC No.1 (IMC stands for International Multi Cache).
These caches are hidden in following (15) European countries:
Austria (A), Belgium (B), Denmark (DK), Finland (FIN), France (F), Germany (D), Great Britain (GB), Hungary (H), Ireland (IRL), Italy (I), Luxembourg (L), Netherlands (NL), Portugal (P), Spain (E) and Sweden (S).
In each country there is a primary cache like this one and a secondary cache that can only be found with hints distributed to all primary caches. The (15) primary caches are named: European IMC No.1 P-X-Yyy and the (15) secondary caches are named: European IMC No.1 S-X-Zzz where x is the country code given above and Yyy and Zzz can be any additional name.
The hints for the secondary caches are printed on lists of hints that are inside the primary caches. As the primary caches are scattered all over Europe it will either require a lot of travelling or - and that is the intention of the European IMC No.1 international cooperation.
If you want to find the secondary cache as well, you should contact finders of other primary European IMC No.1 caches and exchange the hints. And please don't be a poor sport! Never publish the hints anywhere! Not in a log report or on any website. The hints shall only be exchanged / traded between geocachers that found the primary caches and want to search the secondary caches. The European IMC No.1 team wish you good luck!
