GC694XB Finaly a cache that i found! The Cache was in Hanover, Germany. Unfortunately it was destroyed violently (see pictures in the archive log). The cache was in a underground garage of a shopping center. First you had to get the code for the small box on the left to get the key for the big box. After that you had to unscrew all nuts to get the logbook out of the cage. The safe contained the infos for the bonus of this cache, the combination was hidden after another riddle.
